Phineas P. Gage (1823 – May 21, 1860)
was an American railroad construction foreman remembered for his improbableTemplate:Ranchor
survival of an accident in which a large iron rod was driven completely through his head, destroying much of his brain's left frontal lobe, and for that injury's reported effects on his personality and behavior over the remaining twelve years of his life—effects so profound that (for a time at least) friends saw him as "no longer Gage."
The iron's path, per HarlowTemplate:Ranchor
Long known as "the
American Crowbar Case"—once termed "the case which more than all others is calculated to excite our wonder, impair the value of prognosis, and even to subvert our physiological doctrines"[2]—Phineas Gage influenced nineteenth-century discussion about the mind and brain, particularly debate on cerebral localization,Template:RanchorTemplate:Ranchor
and was perhaps the first case to suggest that damage to specific parts of the brain might induce specific personality changes.Template:RanchorTemplate:Ranchor
Gage is a fixture in the curricula of neurology, psychology, and related disciplines (see neuroscience),[3]Template:Ranchor
"a living part of the medical folklore" Template:Ranchor frequently mentioned in books and scientific papers;Template:Ranchor
he even has a minor place in popular culture.[4]
Despite this celebrity the body of established fact about Gage and what he was like (before or after his injury) is small,[c]
which has allowed "the fitting of almost any theory [desired] to the small number of facts we have" Template:Ranchor—Gage acting as a "Rorschach inkblot" [5]
in which proponents of various conflicting theories of the brain were able to find support for their views.
Historically, published accounts (including scientific ones) have almost always severely distorted and exaggerated Gage's behavioral changes, frequently contradicting the known facts.
A report of Gage's physical and mental condition shortly before his death implies that his most serious mental changes were temporary, so that in later life he was far more functional, and socially far better adapted, than in the years immediately following his accident. A social recovery hypothesis suggests that his employment as a stagecoach driver in Chile provided daily structure allowing him to relearn lost social and personal skills.
Life
Background
Cavendish, Vermont, 20 years after Gage's accident. (a)Region of the accident site; (t)Gage's lodgings; (h)Harlow's home and surgery[d]
Gage was the first of five children born to Jesse Eaton Gage and Hannah Trussell (Swetland) Gage, of Grafton County, New Hampshire.[b]
Little is known about his upbringing and education beyond that he was literate.Template:RanchorTemplate:Ranchor
Town doctor John Martyn Harlow described Gage as "a perfectly healthy, strong and active young man, twenty-five years of age, nervo-bilious temperament, five feet six inches [1.68 m] in height, average weight one hundred and fifty pounds [68 kg], possessing an iron will as well as an iron frame; muscular system unusually well developed—having had scarcely a day's illness from his childhood to the date of [his] injury." Template:Ranchor
(In phrenology—then just ending its vogue[9]—nervo-bilious denoted an unusual combination of "excitable and active mental powers" with "energy and strength [of] mind and body [making] possible the endurance of great mental and physical labor".Template:Ranchor[10]: 6 )
Gage may have first worked with explosives on his family's farms or in nearby mines and quarries.Template:Ranchor
He is known to have worked on construction of the Hudson River Railroad near Cortlandt Town, New York,[11]Template:Ranchor
and by the time of his accident he was a blasting foreman (possibly an independent contractor) on railway construction projects.Template:Ranchor
His employers' "most efficient and capable foreman... a shrewd, smart business man, very energetic and persistent in executing all his plans of operation",Template:Ranchor he had even commissioned a custom-made tamping iron—a large iron rod—for use in setting explosive charges.Template:RanchorTemplate:Ranchor
Accident
Line of the Rutland& Burlington Railroad passing through "cut" in rock south of Cavendish. Gage met with his accident while setting explosives to create either this cut or a similar one nearby.[d]
On September 13, 1848, Gage
was directing a work gang blasting rock while preparing the roadbed for the Rutland& Burlington Railroad south of the town of Cavendish, Vermont.
Setting a blast involved boring a hole deep into an outcropping of rock; adding blasting powder, a fuse, and sand;
then compacting this charge into the hole using the tamping iron.[d]
Gage was doing this around 4:30p.m. when
(possibly because the sand was omitted) Template:RanchorTemplate:RanchorTemplate:Ranchor
the iron sparked against the rock and the powder exploded.
Rocketing from the hole, the tamping iron—three feet seven inches (1.1m) long and 1+1⁄4 inches (3.2cm) in diameterTemplate:RanchorTemplate:Ranchor—"entered on the [left] side of [Gage's] face... passing back of the left eye, and out at the top of the head." [e]
Despite nineteenth-century references to Gage as "the American Crowbar Case"[f]
his tamping iron did not have the bend or claw sometimes associated with the term crowbar;
rather, it was a pointed cylinder something like a javelin,Template:Ranchor
"round and rendered comparatively smooth by use":Template:Ranchor
The end which entered first is pointed; the taper being [eleven inches (27cm) long, ending in a 1⁄4-inch (7mm) point] Template:Ranchor... circumstances to which the patient perhaps owes his life. The iron is unlike any other, and was made by a neighbouring blacksmith to please the fancy of its owner.Template:Ranchor
(l)Bigelow's estimate of the iron's path.Template:Ranchor (r)Ratiu etal. and Van Horn etal. concluded Gage's mouth had been open at the crucial moment, and that his skull "hinged" open as the iron passed through.[13]
Weighing 13+1⁄4 pounds (6.0kg),Template:Ranchor the tamping iron was found some 80feet (25m) away,Template:Ranchor "smeared with blood and brain." Template:Ranchor
Gage "was thrown upon his back by the explosion, and gave a few convulsive motions of the extremities, but spoke in a few minutes," walked with little assistance, and sat upright in an oxcart for the 3⁄4-mile (1.2km) ride to his lodgings in town.Template:Ranchor
About thirty minutes after the accident Dr. Edward H. Williams, finding Gage sitting in a chair outside the hotel, was greeted with "one of the great understatements of medical history":Template:Ranchor
When I drove up he said, "Doctor, here is business enough for you." I first noticed the wound upon the head before I alighted from my carriage, the pulsations of the brain being very distinct. The top of the head appeared somewhat like an inverted funnel, as if some wedge-shaped body had passed from below upward. Mr. Gage, during the time I was examining this wound, was relating the manner in which he was injured to the bystanders. I did not believe Mr. Gage's statement at that time, but thought he was deceived. Mr. Gage persisted in saying that the bar went through his head. Mr.G. got up and vomited; the effort of vomiting pressed out about half a teacupful of the brain, which fell upon the floor.[14]
Harlow took charge of the case around 6 p.m.:
You will excuse me for remarking here, that the picture presented was, to one unaccustomed to military surgery, truly terrific; but the patient bore his sufferings with the most heroic firmness. He recognized me at once, and said he hoped he was not much hurt. He seemed to be perfectly conscious, but was getting exhausted from the hemorrhage. His person, and the bed on which he was laid, were literally one gore of blood.[14]
With Williams' assistance[g]
Harlow shaved the scalp around the region of the tamping iron's exit, then removed coagulated blood, small bone fragments, and an ounce [30g] of protruding brain.
After probing for foreign bodies and replacing two large detached pieces of bone, Harlow closed the wound with adhesive straps, leaving it partially open for drainage;Template:Ranchor
the entrance wound in the cheek was bandaged only loosely, for the same reason. A wet compress was applied, then a nightcap, then further bandaging to secure these dressings. Harlow also dressed Gage's hands and forearms (which along with his face had been "deeply burned") and ordered that Gage's head be kept elevated.
Late that evening Harlow noted: "Mind clear. Constant agitation of his legs, being alternately retracted and extended like the shafts of a fulling mill. Says he 'does not care to see his friends, as he shall be at work in a few days.'" [14]
Convalescence
Despite his own optimism, Gage's convalescence was long, difficult, and uneven.
Though recognizing his mother and uncle (summoned from Lebanon, New Hampshire, thirty miles awayTemplate:RanchorTemplate:Ranchor) on the morning after the accident, on the second day he "lost control of his mind, and became decidedly delirious".
Two days later he was again "rational... knows his friends",
and after a week's further progress Harlow entertained, for the first time, the thought "that it was possible for Gage to recover... This improvement, however, was of short duration." [14]
The Boston Post for Sep.21, 1848 (understating the diameter of Gage's tamping iron and overstating damage to his jaw)[e]
Beginning September25Template:Ranchor Gage was semi-comatose, "seldom speaking unless spoken to, and then answering only in monosyllables",
and the next day Harlow noted, "Failing strength... coma deepened; the globe of the left eye became more protuberant, with [granulation tissue][h]
pushing out rapidly from the internal canthus [as well as] from the wounded brain, and coming out at the top of the head."
After another day, "The exhalations from the mouth and head [are] horribly fetid. Comatose, but will answer in monosyllables if aroused. Will not take nourishment unless strongly urged. The friends and attendants are in hourly expectancy of his death, and have his coffin and clothes in readiness." [14]
Galvanized, Harlow "cut off the [granulation tissue] sprouting out from the top of the brain and filling the opening, and made free application of caustic [i.e. crystalline silver nitrate]Template:Ranchor to them. With a scalpel I laid open the [frontalis muscle,Template:Ranchor from the exit wound to the top of the nose] and immediately there were discharged eight ounces [250ml] of ill-conditioned pus, with blood, and excessively fetid." [i]
("Gage was lucky to encounter Dr. Harlow when he did," wrote Barker. "Few doctors in 1848 would have had the experience with cerebral abscess with which Harlow left [Jefferson Medical College]
and which probably saved Gage's life." Template:Ranchor
See §Factors favoring Gage's survival.)
On October 7, Gage "succeeded in raising himself up, and took one step to his chair". One month later he was walking "up and down stairs, and about the house, into the piazza", and while Harlow was absent for a week, Gage was "in the street every day except Sunday", his desire to return to his family in New Hampshire being "uncontrollable by his friends... got wet feet and a chill." He soon developed a fever, but by mid-November he was "feeling better in every respect... walking about the house again". Harlow's prognosis at this point: Gage "appears to be in a way of recovering, if he can be controlled." [14]
Subsequent life and travels
By November 25, Gage was strong enough to return to his parents' home in Lebanon, New Hampshire, where by late December he was "riding out, improving both mentally and physically" Template:Ranchor
and (as recorded in the notes of a physician who spoke to Gage's mother) "abt. February he was able to do a little work abt.ye horses& barn, feedg.ye cattle&c; that as ye time for ploughing came he was able to do half a day's work after that& bore it well." [23]Template:Ranchor
Injuries
"Disfigured yet still handsome".Template:Ranchor Note ptosis of the left eye and abscess scar on forehead.
In April 1849 Gage returned to Cavendish and paid a visit to Harlow, who noted at that time loss of vision (and ptosis) of the left eye,[j]
a large scar on the forehead (from Harlow's draining of the abscess) Template:Ranchor and
upon the top of the head... a deep depression, two inches by one and one-half inches [5cm by 4cm] wide, beneath which the pulsations of the brain can be perceived. Partial paralysis of the left side of the face. His physical health is good, and I am inclined to say he has recovered. Has no pain in head, but says it has a queer feeling which he is not able to describe.Template:Ranchor
Though a year later some physical weakness remained,Template:Ranchor[24]
Harlow later wrote that "physically, the recovery was quite complete during the four years immediately succeeding the injury".Template:Ranchor
New England and New York (1849–1852)
In November 1849 Henry Jacob Bigelow, the Professor of Surgery at Harvard Medical School, brought Gage to Boston "at very considerable expense [and after having] satisfied himself that the bar had actually passed through the man's head",[25]: 149 presented him to a meeting of the Boston Society for Medical Improvement and (possibly) to a Medical School class.Template:RanchorTemplate:Ranchor[26]
(This may have been one of the earliest cases of a patient entering a hospital primarily to further medical research, rather than for treatment.) [27]
Unable to return to his railroad work (see §Early observations)
Gage appeared for a time, with his iron, at Barnum's American Museum in New York City
(not the later Barnum's circus—there is no evidence Gage ever exhibited with a troupe or circus, or on a fairground).Template:RanchorTemplate:RanchorTemplate:RanchorTemplate:Ranchor
Advertisements have also been found for public appearances by Gage—which he may have arranged and promoted himself—in New Hampshire and Vermont,Template:Ranchor
supporting Harlow's statement that Gage made public appearances in "most of the larger New England towns".Template:RanchorTemplate:Ranchor
(Years later Bigelow wrote that Gage had been "a shrewd and intelligent man and quite disposed to do anything of that sort to turn an honest penny", but had given up such efforts because "[that] sort of thing has not much interest for the general public".Template:Ranchor[28]: 28 Template:Ranchor)
For about eighteen months he worked for the owner of a livery and coach service in Hanover, New Hampshire.Template:RanchorTemplate:Ranchor
Chile and California (1852–1860)
In August 1852, Gage was invited to Chile to work as a long-distance stagecoach driver there, "caring for horses, and often driving a coach heavily laden and drawn by six horses" on the Valparaiso–Santiago route.Template:RanchorTemplate:Ranchor
After his health began to fail in mid-1859,Template:Ranchor[k]
Gage left Chile for San Francisco, arriving (in his mother's words) "in a feeble condition, having failed very much since he left New Hampshire... Had many ill turns while in Valparaiso, especially during the last year, and suffered much from hardship and exposure."
In San Francisco he recovered under the care of his mother and sister,Template:Ranchor
who had relocated there from New Hampshire around the time Gage went to Chile.Template:Ranchor
Then, "anxious to work", he found employment with a farmer in Santa Clara.Template:Ranchor
Death
"It is regretted that an autopsy could not have been had, so that the precise condition of the encephalon at the time of his death might have been known. [Therefore] the mother and friends, waiving the claims of personal and private affection, with a magnanimity more than praiseworthy, at my request have cheerfully placed this skull in my hands, for the benefit of science." Gage's skull (sawn to show interior) and iron, photographed for Harlow in 1868.[32]
In February 1860[k] Gage had several epileptic seizures.Template:RanchorTemplate:Ranchor
He lost his job, and (wrote Harlow) as the seizures increased in frequency and severity over the succeeding three months he "continued to work in various places [though he] could not do much".
On May 18 he "left Santa Clara and went home to his mother. At 5o'clock, A.M., on the 20th, he had a severe convulsion. The family physician was called in, and bled him. The convulsions were repeated frequently during the succeeding day and night," Template:Ranchor and he died during status epilepticus,Template:Ranchor
in or nearTemplate:Ranchor San Francisco, late on May21, 1860,
just under twelve years after his injury.
He was buried in San Francisco's Lone Mountain Cemetery.[k]
Exhumation
In 1866, Harlow (who had "lost all trace of [Gage], and had well nigh abandoned all expectation of ever hearing from him again") somehow learned that Gage had died in California, and made contact with his family there.
At Harlow's request Gage's grave was opened long enough to remove his skull, which the family then personally delivered to Harlow,Template:RanchorTemplate:RanchorTemplate:Ranchor
who was by now a prominent physician, businessman, and civic leader in Woburn, Massachusetts.Template:RanchorTemplate:Ranchor
About a year after the accident, Gage had given his tamping iron to Harvard Medical School's Warren Anatomical Museum, but he later reclaimed itTemplate:Ranchor[33]Template:Ranchor
and made what he called "my iron bar" Template:RanchorTemplate:Ranchor
his "constant companion during the remainder of his life";Template:Ranchor
now it too was delivered by Gage's family to Harlow.Template:Ranchor
(Though some accounts assert that Gage's iron had been buried with him, there is no evidence for this.Template:Ranchor)
After studying them for a triumphalTemplate:Ranchor
1868 retrospective paper on GageTemplate:Ranchor
Harlow redeposited the iron—this time with the skull—in the Warren Museum, where they remain on display today.[34]
The iron bears the following inscription, commissioned by Bigelow in conjunction with the iron's first deposit in the Museum[33]
(though the date it gives for the accident is one day off, and Phinehas is not the way Gage spelled his nameTemplate:Ranchor):
This is the bar that was shot through the head of Mr Phinehas[sic] P.Gage at Cavendish, Vermont, Sept.14,[sic] 1848. He fully recovered from the injury& deposited this bar in the Museum of the Medical College of Harvard University. Phinehas P.Gage Lebanon GraftonCy N–H Jan6 1850.Template:Ranchor
The date Jan 6 1850 falls within the period during which Gage was in Boston under Bigelow's observation.Template:RanchorTemplate:RanchorTemplate:Ranchor

Brain damage and mental changes
The left frontal lobe (red), the forward portion of which was damaged by Gage's injury, per Harlow's digital examination and the digital analyses of Ratiu etal. and Van Horn etal.Template:RanchorTemplate:Ranchor
Extent of brain damage
False-color representations of cerebral fiber pathways affected, per Van Horn etal.Template:Ranchor
Debate about whether the
trauma and subsequent infection had damaged both of Gage's frontal lobes (left and right), or only the left, began almost immediately after his accident.[l]
The 1994 conclusion of Hanna Damasio etal., that both frontal lobes were damaged, was drawn not from Gage's skull but from a "Gage-like" one—a cadaver skull deformed to match the dimensions of Gage's.Template:Ranchor[40]: 1103-4
Using CT scans of Gage's actual skull, Ratiu etal.Template:Ranchor and Van Horn etal.Template:Ranchor
both rejected that conclusion, agreeing with Harlow's belief—based on probing Gage's wounds with his fingers[41]—that only the left frontal lobe had been damaged.Template:Ranchor
In addition, Ratiu etal. noted that the opening between the roof of the mouth and the base of the cranium (created as the iron passed through) has a diameter about half that of the iron itself;
combining this with the hairline fracture running from behind the exit region down the front of the skull,
they concluded that the skull "hinged" open as the iron entered from below, then (once the iron had exited at the top) was pulled closed by the resilience of soft tissues.Template:RanchorTemplate:Ranchor
Van Horn etal. concluded that damage to Gage's white matter (of which they made detailed estimates) was as or more significant to Gage's mental changes than cerebral cortex (gray matter) damage.Template:Ranchor
First-hand reports of mental changes
Gage certainly displayed some kind of change in behavior after his injury,Template:Ranchor
but the nature, extent, and duration of this change have been difficult to establish.
Only a handful of sources give direct information on what Gage was like (either before or after the accident),[c]
the mental changes described after his death were much more dramatic than anything reported while he was alive,Template:Ranchor and few sources are explicit about the period of Gage's life to which their various descriptions of him (which vary widely in their implied level of functional impairment) are meant to apply.Template:Ranchor
Early observations (1849–1852)
Harlow described the pre-accident Gage as hard-working, responsible, and "a great favorite" with the men in his charge, his employers having regarded him as "the most efficient and capable foreman in their employ". But these same employers, after Gage's accident, "considered the change in his mind so marked that they could not give him his place again":
The equilibrium or balance, so to speak, between his intellectual faculties and animal propensities, seems to have been destroyed. He is fitful, irreverent, indulging at times in the grossest profanity (which was not previously his custom), manifesting but little deference for his fellows, impatient of restraint or advice when it conflicts with his desires, at times pertinaciously obstinate, yet capricious and vacillating, devising many plans of future operations, which are no sooner arranged than they are abandoned in turn for others appearing more feasible. A child in his intellectual capacity and manifestations, he has the animal passions of a strong man. Previous to his injury, although untrained in the schools, he possessed a well-balanced mind, and was looked upon by those who knew him as a shrewd, smart business man, very energetic and persistent in executing all his plans of operation. In this regard his mind was radically changed, so decidedly that his friends and acquaintances said he was "no longer Gage".Template:Ranchor
"I dressed him, God healed him." Dr. J.M. Harlow, who attended Gage after the "rude missile had been shot through his brain",[42] and obtained his skull for study after his death, in later life. His interest in phrenology prepared him to accept that Gage's injury changed his behavior.[43]"The leading feature of this case is its improbability." Harvard's H.J. Bigelow in 1854. His training predisposed him to minimize Gage's behavioral changes.Template:Ranchor
This description ("now routinely quoted", says KotowiczTemplate:Ranchor)
is from Harlow's observations set down soon after the accident,Template:RanchorTemplate:Ranchor
but Harlow—perhaps hesitant to describe his patient negatively while he was still aliveTemplate:Ranchor—left these observations unpublished until 1868, after Gage had died and his family had supplied "what we so much desired to see" (as Harlow termed Gage's skull).Template:Ranchor
In the interim, Harlow's 1848 report, published just as Gage was emerging from his convalescence, only hinted at psychological symptoms:Template:Ranchor
The mental manifestations of the patient, I leave to a future communication. I think the case... is exceedingly interesting to the enlightened physiologist and intellectual philosopher.Template:Ranchor
But after Bigelow termed Gage "quite recovered in faculties of body and mind", with only "inconsiderable disturbance of function",Template:Ranchor
a rejoinder in the American Phrenological Journal—
That there was no difference in his mental manifestations after the recovery isnot true... The man was gross, profane, coarse, and vulgar, to such a degree that his society was intolerable to decent people.[44]
—was apparently based on information anonymously supplied by Harlow.Template:Ranchor
Barker explains these contradictory evaluations (only six months apart) by differences in Bigelow's and Harlow's educational backgrounds:
Harlow's interest in phrenology prepared him to accept the change in character as a significant clue to cerebral function which merited publication. Bigelow had [been taught] that damage to the cerebral hemispheres had no intellectual effect, and he was unwilling to consider Gage's deficit significant... The use of a single case [including Gage's] to prove opposing views on phrenology was not uncommon.Template:Ranchor
Later observations (1852–1858)
In 1860, an American physician who had known Gage "well" in Chile reported that Gage remained "engaged in stage driving [and] in the enjoyment of good health, with no impairment whatever of his mental faculties." [45]Template:Ranchor
Together with the fact that Gage was hired by his employer in advance, in New England, to be part of the new coaching enterprise in Chile,Template:RanchorTemplate:Ranchor
this implies that Gage's most serious mental changes had been temporary, so that the "fitful, irreverent... capricious and vacillating" Gage described by Harlow immediately post-accident became, over time, far more functional and socially far better adapted.Template:RanchorTemplate:Ranchor
This conclusion is reinforced (writes psychologist Malcolm Macmillan) by the responsibilities and challenges associated with stagecoach work such as that done by Gage in Chile, including the requirement that drivers "be reliable, resourceful, and possess great endurance. But above all, they had to have the kind of personality that enabled them to get on well with their passengers." [46]Template:RanchorTemplate:Ranchor
A day's work for Gage meant "a 13-hour journey over 100 miles of poor roads, often in times of political instability or frank revolution. All this—in a land to whose language and customs Phineas arrived an utter stranger—militates as much against permanent disinhibition [i.e. an inability to plan and self-regulate] as do the extremely complex sensory-motor and cognitive skills required of a coach driver." Template:RanchorTemplate:Ranchor
(A visitor wrote that "the departure of the coach was always a great event at Valparaiso—a crowd of ever-astonished Chilenos assembling every day to witness the phenomenon of one man driving six horses." [47]: 73 )
Social recovery
Macmillan hypothesizes that this contrast—between Gage's early, versus later, post-accident behavior—reflect Gage's "[gradual change] from the commonly portrayed impulsive and uninhibited person into one who made a reasonable 'social recovery'",[48]
citing persons with similar injuries for whom "someone or something gave enough structure to their lives for them to relearn lost social and personal skills":Template:Ranchor
Phineas' survival and rehabilitation demonstrated a theory of recovery which has influenced the treatment of frontal lobe damage today. In modern treatment, adding structure to tasks by, for example, mentally visualising a written list, is considered a key method in coping with frontal lobe damage.Template:Ranchor
According to a contemporary account by visitors to Chile,Template:Ranchor Gage would have had to
rise early in the morning, prepare himself, and groom, feed, and harness the horses; he had to be at the departure point at a specified time, load the luggage, charge the fares and get the passengers settled; and then had to care for the passengers on the journey, unload their luggage at the destination, and look after the horses. The tasks formed a structure that required control of any impulsiveness he may have had.Template:Ranchor
En route (Macmillan continues):
much foresight was required. Drivers had to plan for turns well in advance, and sometimes react quickly to manoeuvre around other coaches, wagons, and birlochos travelling at various speeds ... Adaptation had also to be made to the physical condition of the route: although some sections were well-made, others were dangerously steep and very rough.
Thus Gage's stagecoach work—"a highly structured environment in which clear sequences of tasks were required [but within which] contingencies requiring foresight and planning arose daily"—resembles rehabilitation regimens first developed by Soviet neuropsychologist Alexander Luria for the reestablishment of self-regulation in World WarII soldiers suffering frontal lobe injuries.Template:Ranchor
A neurological basis for such recoveries may be found in emerging evidence "that damaged [neural] tracts may re-establish their original connections or build alternative pathways as the brain recovers" from injury.[48]
Macmillan adds that if Gage made such a recovery—if he eventually "figured out how to live" (as Fleischman put it) Template:Ranchor
despite his injury—then it "would add to current evidence that rehabilitation can be effective even in difficult and long-standing cases";Template:Ranchor
and if Gage could achieve such improvement without medical supervision, "what are the limits for those in formal rehabilitation programs?" Template:Ranchor
As author Sam Kean put it, "If even Phineas Gage bounced back—that's a powerful message of hope." Template:Ranchor
Exaggeration and distortion of mental changes
A moral man, Phineas Gage Tamping powder down holes for his wage Blew his special-made probe Through his left frontal lobe Now he drinks, swears, and flies in a rage.
—AnonymousTemplate:Ranchor
Macmillan's analysis of scientific and popular accounts of Gage found that they almost always distort and exaggerate his behavioral changes well beyond anything described by anyone who had contact with him.[c]
In the words of Barker,Template:Ranchor "As years passed, the case took on a life of its own, accruing novel additions to Gage's story without any factual basis"; even today (writes historian Zbigniew Kotowicz) "Most commentators still rely on hearsay and accept what others have said about Gage, namely, that after the accident he became a psychopath..." Template:Ranchor
and Grafman has written that "the details of [Gage's] social cognitive impairment have occasionally been inferred or even embellished to suit the enthusiasm of the story teller..." Template:Ranchor
Behaviors ascribed to the post-accident Gage which are either unsupported by, or in contradiction to, the known facts include mistreatment of wife and children (of which Gage had neither);[50]
inappropriate sexual behavior, promiscuity, or impaired sexuality;[51]
lack of forethought, of concern for the future, or of capacity for embarrassment;
parading his self-misery, and vainglory in showing his wounds;[52]
inability[53] or refusal[54] to hold a job;
irresponsibility and untrustworthiness;[55]
aggressiveness and violence;[56]
vagrancy and begging;[57]
plus drifting,[58] drinking,[59]
bragging,[60] lying,[61] brawling,[62] bullying,[63]psychopathy,[64]
inability to make ethical decisions, loss of all respect for social conventions, acting "like an idiot",[65]
and dying "due to a debauch".[66]
None of these behaviors is mentioned by anyone who had met Gage or even his family;[c]
as Kotowicz put it, "Harlow does not report a single act that Gage should have been ashamed of." Template:Ranchor
Gage is "a great story for illustrating the need to go back to original sources", writes Macmillan.[68]
For example, a passage by Harlow— "'...continued to work in various places;' could not do much, changing often, 'and always finding something that did not suit him in every place he tried'" Template:Ranchor—has been misinterpreted[69]
as meaning Gage could not hold a regular job after his accident,[70]
"was prone to quit in a capricious fit or be let go because of poor discipline",[71]: 8-9
"never returned to a fully independent existence",[40]: 1102
and died "in careless dissipation"[72]
in "the custody of his parents." [73]
In fact, after his initial post-recovery months spent traveling and exhibiting,
Gage supported himself—at a total of two jobs—from early 1851 until just before his death in 1860.Template:Ranchor
(Harlow's "changing often" refers only to Gage's final months, after convulsions had set in,
and even then he remained "anxious to work".Template:RanchorTemplate:Ranchor
In Kotowicz's words, "What Harlow is telling us is clear and unambiguous: Gage returns from South America to his mother to recuperate. As soon as he is fit, he goes back to work with horses, which is what he has been doing for years." Template:Ranchor)
Theoretical use and misuse
Though Gage is considered the "index case for personality change due to frontal lobe damage" Template:Ranchor[74]Template:RanchorTemplate:Ranchor
his scientific value is undermined by the uncertain extent of his brain damageTemplate:Ranchor and the limited understanding of his behavioral changes.[c]
Instead, Macmillan writes, "Phineas' story is [primarily] worth remembering because it illustrates how easily a small stock of facts becomes transformed into popular and scientific myth," Template:Ranchor
the paucity of evidence having allowed "the fitting of almost any theory [desired] to the small number of facts we have".Template:Ranchor
A similar concern was expressed as far back as 1877, when British neurologist David Ferrier (writing to Harvard's Henry Pickering Bowditch in an attempt "to have this case definitely settled")

More recently, neurologist Oliver Sacks refers to the "interpretations and misinterpretations, from 1848 to the present," of Gage,[76]
and MacmillanTemplate:RanchorTemplate:RanchorTemplate:Ranchor surveys theoretical use and misuse of Gage.
Cerebral localization
In the nineteenth-century controversy over whether the various mental functions are or are not localized in specific regions of the brain, both sides managed to enlist Gage in support of their theories.Template:RanchorTemplate:Ranchor
For example, after Dupuy wrote that Gage proved that the brain is not localized (characterizing him as a "striking case of destruction of the so-called speech centre without consequent aphasia") [36]
Ferrier made a "devastating reply" in his 1878 Goulstonian Lectures, "On the Localisation of Cerebral Disease", of which Gage (and the woodcuts of his skull and iron from Harlow's 1868 paper) were "an absolutely dominating feature".[37]Template:Ranchor
Phrenology
Phrenologists contended that destruction of the mental "organs" of Veneration and Benevolence caused Gage's behavioral changes. Harlow may have believed that the "Organ of Comparison" was damaged.
Throughout the nineteenth century, adherents of phrenology contended that Gage's mental changes (his profanity, for example[44]Template:Ranchor) stemmed from destruction of his mental "organ of Benevolence"—as phrenologists saw it, the part of the brain responsible for "goodness, benevolence, the gentle character... [and] to dispose man to conduct himself in a manner conformed to the maintenance of social order"—and/or the adjacent "organ of Veneration"—related to religion and God, and respect for peers and those in authority.Template:Ranchor[77][1]
(Phrenology held that the organs of the "grosser and more animal passions are near the base of the brain; literally the lowest and nearest the animal man [while] highest and farthest from the sensual are the moral and religions feelings, as if to be nearest heaven."
Thus Veneration and Benevolence are at the apex of the skull—the region of exit of Gage's tamping iron.[78])
Harlow wrote that Gage, during his convalescence, did not "estimate size or money accurately [and] would not take $1000 for a few pebbles";Template:Ranchor
by this he may have been implying damage to phrenology's "Organ of Comparison".Template:Ranchor
Psychosurgery and lobotomy
It is frequently said that what happened to Gage played a part in the later development of various forms of psychosurgery—particularly lobotomy[79]: 341 Template:Ranchor—or
even that Gage's accident constituted "the first lobotomy".[80]
Aside from the question of why the unpleasant changes usually (if hyperbolically) attributed to Gage would inspire surgical imitation, there is no such link, according to Macmillan:
There is simply no evidence that any of these operations were deliberately designed to produce the kinds of changes in Gage that were caused by his accident, nor that knowledge of Gage's fate formed part of the rationale for themTemplate:Ranchor... [W]hat his case did show came solely from his surviving his accident: major operations [such as for tumors] could be performed on the brain without the outcome necessarily being fatal.Template:Ranchor
Somatic marker hypothesis
A.Damasio, in support of his somatic marker hypothesis (relating decision-making to emotions and their biological underpinnings), draws parallels between behaviors he attributes to Gage and those of modern patients with damage to the orbitofrontal cortex and amygdala.[71]: ch3 [81]
But A.Damasio's depiction of Gage has been criticized by Kotowicz as
grotesque fabrication... ["perpetrating"] the myth of Gage the psychopath... Damasio changes [Harlow's] narrative, omits facts, and adds freely... It seems that the growing commitment to the frontal lobe doctrine of emotions brought Gage to the limelight and shapes how he is described. [m]
As Kihlstrom put it:
[M]any modern commentators exaggerate the extent of Gage's personality change, perhaps engaging in a kind of retrospective reconstruction based on what we now know, or think we do, about the role of the frontal cortex in self-regulation.Template:Ranchor
Portraits
Inscription on iron as seen in portrait: [Phine]has P. Gage at Cavendish, Vermont, Sept. 14, 1848. He fullyThe second portrait of Gage to be identified (2010) [a]
Two daguerreotype portraits of Gage, identified in 2009 and 2010,[a]
are the only likenessesTemplate:RanchorTemplate:RanchorTemplate:Ranchor of him known other than a life mask taken for Bigelow in late 1849 (and now in the Warren Museum along with Gage's skull and iron).Template:Ranchor[25]: 149 Template:Ranchor
The first shows "a disfigured yet still-handsome" GageTemplate:Ranchor
with one eye closed and scars clearly visible, "well dressed and confident, even proud" Template:Ranchor
and holding his iron, on which portions of its inscription can be made out.Template:Ranchor
(For decades the portrait's owners had imagined the subject was an injured whaler with his harpoon. Template:Ranchor)
The second portrait, copies of which are in the possession of two different branches of the Gage family, shows Gage in a somewhat different pose, wearing a different shirt and different tie, but the same waistcoat and possibly the same jacket.Template:Ranchor
Authenticity was confirmed in several ways (including photo-overlaying the inscription, as seen in the portraits, against that on the actual tamping iron, and matching the subject's injuries to those preserved in the life maskTemplate:Ranchor)
but about when, where, and by whom they were taken nothing is known, except that they were created no earlier than January 1850 (when the inscription was added to the tamping iron),Template:Ranchor
on different occasions, and are likely by different photographers.Template:Ranchor
The portraits reinforce the social recovery hypothesis already described (see §Social recovery).Template:Ranchor[82]
"That [Gage] was any form of vagrant following his injury is belied by these remarkable images", wrote Van Horn etal.Template:Ranchor
"Although just one picture," Kean commented in reference to the first image discovered, "it exploded the common image of Gage as a dirty, disheveled misfit. This Phineas was proud, well-dressed, and disarmingly handsome." Template:Ranchor
Early medical attitudes
A tone of amused wonderment was common in nineteenth-century medical writing about Gage (as well as about victims of other unlikely-sounding brain-injury accidents, including encounters with axes, bolts, low bridges, exploding firearms, a revolver shot to the nose, more tamping irons, and "even falling gum tree branches").Template:Ranchor
The Boston Medical& Surgical Journal, for example, termed Gage "the patient whose cerebral organism had been comparatively so little disturbed by its abrupt and intrusive visitor." [33]
Skepticism
Barker notes that Harlow's original 1848 report of Gage's recovery "was widely disbelieved, for obvious reasons" Template:Ranchor
and Harlow himself, in his 1868 retrospective, recalled this early skepticism:
The case occurred nearly twenty years ago, in an obscure country town..., was attended and reported by an obscure country physician, and was received by the Metropolitan doctors with several grains of caution, insomuch that many utterly refused to believe that the man had risen, until they had thrust their fingers into the hole [in] his head, [see Doubting Thomas] and even then they required of the Country Doctor attested statements, from clergymen and lawyers, before they could or would believe—many eminent surgeons regarding such an occurrence as a physiological impossibility, the appearances presented by the subject being variously explained away.
"A distinguished Professor of Surgery in a distant city", Harlow said, had even dismissed Gage as a "Yankee invention".Template:Ranchor
According to the Boston Medical and Surgical Journal, it was the 1850 report on Gage by Bigelow—Harvard's Professor of Surgery and "a majestic and authoritative figure on the medical scene of those times" [27]—that "finally succeeded in forcing [the case's] authenticity upon the credence of the profession... as could hardly have been done by any one in whose sagacity and surgical knowledge his confrères had any less confidence".[33][citation needed]
Noting that, "The leading feature of this case is its improbability... This is the sort of accident that happens in the pantomime at the theater, not elsewhere", and calling the case "perhaps unparalleled in the annals of surgery", Bigelow emphasized that though "at first wholly skeptical, I have been personally convinced".[n]
Nonetheless (Bigelow wrote just before Harlow's 1868 presentation of Gage's skull) though "the nature of [Gage's] injury and its reality are now beyond doubt... I have recd a letter within a month [purporting] to prove that... the accident could not have happened ",Template:Ranchor
and two years later Jackson was still able to write that
The very small amount of attention that has been given to [the Gage case] can only be explained by the fact that it far transcends any case of recovery from injury of the head that can be found in the records of surgery. It was too monstrous for belief... [25]: 149
Standard for other brain injuries
"[Few objects] have attracted more visitors and spread farther the fame of the Museum" [27] than its "most valuable specimen".[25]: v
As the reality of Gage's accident and survival gained credence, it became "the standard against which other injuries to the brain were judged".
After a miner survived traversal of his skull by a gas pipe (extracted "not without considerable difficulty and force, owing to a bend in the portion of the rod in his skull")
his physician invoked Gage as the "only case comparable with this, in the amount of brain injury, that I have seen reported".[o]
Often these comparisons carried hints of competitiveness, humor, or both,Template:Ranchor
as when a Kentucky doctor, reporting a patient's survival of a gunshot to the nose, bragged:
If you Yankees can send a tamping bar through a fellow's brain and not kill him, I guess there are not many can shoot a bullet between a man's mouth and his brains, stopping just short of the medulla oblongata, and not touch either.[85]
Similarly, when a lumbermill foreman returned to work soon after a saw cut three inches (8cm) into his skull from just between the eyes to behind the top of his head, his surgeon (who had removed from this wound "thirty-two pieces of bone, together with considerable sawdust") termed the case "second to none reported, save the famous tamping-iron case of Dr. Harlow", though apologizing that "I cannot well gratify the desire of my professional brethren to possess [the patient's] skull, until he has no further use for it himself." [86]
As these and other remarkable brain-injury survivals accumulated, the Boston Medical& Surgical Journal (1869) pretended to wonder whether the brain has any function at all: "Since the antics of iron bars, gas pipes, and the like skepticism is discomfitted, and dares not utter itself. Brains do not seem to be of much account now-a-days." [87]
The Transactions of the Vermont Medical Society was similarly facetious:
"'The times have been,'
says Macbeth [ActIII], 'that when the brains were out the man would die. But now they rise again.' Quite possibly we shall soon hear that some German professor is exsecting it." [12]: 53-4
Factors favoring Gage's survival
"I have the pleasure of being able to present to you [a case] without parallel in the annals of surgery." Template:Ranchor Harlow's 1868 presentation to the Massachusetts Medical SocietyTemplate:Ranchor of Gage's skull, iron, and post-accident history.
Harlow saw Gage's survival as demonstrating "the wonderful resources of the system in enduring the shock and in overcoming the effects of so frightful a lesion, and as a beautiful display of the recuperative powers of nature", and listed what he saw as the circumstances favoring it:
1st. The subject was the man for the case. His physique, will, and capacity of endurance, could scarcely be excelled.Template:Ranchor
See Harlow's description of the pre-accident Gage at §Background (above).
2d. The shape of the missile—being pointed, round and comparatively smooth, not leaving behind it prolonged concussion or compression.Template:Ranchor
Despite its very large diameter and mass (compared to a weapon-fired projectile) the tamping iron's relatively low velocity drastically reduced the energy available to compressive and concussive "shock waves".Template:Ranchor[88][89]
Ratiu etal.'s conclusion, that Gage's skull "hinged open" as the iron passed through,Template:Ranchor
implies a further reduction in such effects because of the increased volume available into which the brain could shift temporarily.[citation needed]
Harlow continued:
3d. The point of entrance outside of the superior maxillary bone—[the tamping iron] did little injury until it reached the floor of the cranium, when, at the same time that it did irreparable damage, it [created the] opening in the base of the skull, for drainage, [without which] recovery would have been impossible.Template:Ranchor
Barker writes that "[Head injuries] from falls, horse kicks, and gunfire, were well known in pre–Civil War America [and] every contemporary course of lectures on surgery described the diagnosis and treatment" of such injuries. But to Gage's benefit, surgeon Joseph Pancoast had performed "his most celebrated operation for head injury before Harlow's medical school class, [trephining] to drain the pus, resulting in temporary recovery. Unfortunately, symptoms recurred and the patient died. At autopsy, reaccumulated pus was found: granulation tissue had blocked the opening in the dura." By keeping the exit wound open and elevating Gage's head to encourage drainage from the cranium through the hole in the roof of the mouth, Harlow "had not repeated Professor Pancoast's mistake." Template:RanchorTemplate:Ranchor[90]
Finally,
4th. The portion of the brain traversed was, for several reasons, the best fitted of any part of the cerebral substance to sustain the injury.Template:Ranchor
Precisely what Harlow's "several reasons" were is unclear,
but he was likely referring, at least in part, to the understanding (slowly developing since ancient times) that injuries to the rear of the brain are especially dangerous, because they frequently interrupt vital functions such as breathing and circulation.Template:Ranchor
As British surgeon James Earle wrote in 1790, "[A] great part of the cerebrum may be taken away without destroying the animal, or even depriving it of its faculties, whereas the cerebellum will scarcely admit the smallest injury, without being followed by mortal symptoms." Template:Ranchor[91]
Ratiu etal. and Van Horn etal. both concluded that the superior sagittal sinus must have remained intact, for otherwise Gage would almost certainly have suffered fatal blood loss or air embolism.Template:RanchorTemplate:Ranchor
As to his own role in Gage's survival, Harlow merely averred, "I can only say... with good old Ambroise Paré, I dressed him, God healed him",Template:Ranchor
but Macmillan calls this self-assessment far too modest.Template:RanchorTemplate:RanchorTemplate:Ranchor
Noting that Harlow had been a "relatively inexperienced local physician... graduated four and a half years earlier",Template:Ranchor
Macmillan's discussion of Harlow's "skillful and imaginative adaptation" of "conservative and progressive elements from the available therapies to the particular needs posed by Gage's injuries" emphasizes that he "did not apply rigidly what he had learned", for example foregoing an exhaustive search for bone fragments (which risked hemorrhage and further brain injury) and applying caustic silver nitrate to the granulation tissue instead of excising it (which risked hemorrhage) or forcing it into the wound (which risked compressing the brain).Template:Ranchor

Notes
^ abcThe 2009-identified image is from the collection of Jack and Beverly Wilgus.Template:RanchorTemplate:RanchorTemplate:RanchorTemplate:Ranchor
Like almost all daguerreotypes it shows its subject laterally (left-right) reversed, making it appear that Gage's right eye is injured.Template:RanchorTemplate:Ranchor
However, all Gage's injuries, including to his eye, were on the left;
therefore in presenting the image here a second, compensating reversal has been applied so as to show Gage as he appeared in life.Template:RanchorTemplate:Ranchor
The 2010-identified image is in the possession of Tara Gage Miller of Texas; an identical image belongs to Phyllis Gage Hartley of New Jersey.Template:Ranchor
(Both are descended from Gage's brother Roswell Rockwell Gage.Template:Ranchor)
Unlike the Wilgus portrait, which is itself a daguerreotype, the Miller and Hartley images are 19th-century photographic reproductions of a common original which remains undiscovered, itself a daguerreotype or other laterally reversing early-process photograph;Template:Ranchor here again a compensating reversal has been applied.Template:Ranchor
^ abcMacmillanTemplate:Ranchor
discusses Gage's ancestry and early life.
His parents were married April27, 1823.
The birthdate July 9, 1823 is given by a Gage genealogy[6]
without citation,Template:Ranchor but is consistent with agreement among contemporary sources[7]
that Gage was 25 years old on the date of his accident, and with his age (36years) as given in undertaker's records after his death in May1860.Template:Ranchor
Possible homes in childhood and youth are Lebanon or nearby East Lebanon, Enfield, and/or Grafton (all in Grafton County, New Hampshire), though Harlow refers to Lebanon in particular as Gage's "native place" Template:Ranchor
and "his home" Template:Ranchor
(likely that of his parents),Template:Ranchor
to which Gage returned ten weeksTemplate:Ranchor after his accident.
There is nothing to indicate what Gage's middle initial P[8]
stood for.
His mother's first, middle, and maiden names are variously given as (respectively) Hannah or Hanna; Trussell, Trusel, or Trussel; and Swetland, Sweatland, or Sweetland.Template:Ranchor
^ abcdeMacmillanTemplate:RanchorTemplate:RanchorTemplate:Ranchor
compares accounts of Gage to one another and against the known facts, as well as contrasting Gage's celebrity—he is mentioned in 91% of a sample of introductory psychology textbooks published 2012–2014[67]—with what was, until recently, the lack of any major study of him and dearth of papers solely or mainly about him.Template:Ranchor
Until 2008Template:RanchorTemplate:Ranchor the available sources offering significant information on Gage, and for which there is any evidence at all (even merely the source's own claim) of contact with him or with his family, were limited to Harlow (1848, 1849, 1868);Template:RanchorTemplate:RanchorTemplate:Ranchor Bigelow (1850);Template:Ranchor and Jackson (1849, 1870).[23][25]
Macmillan notes that descriptions of Gage's behavior total just 300 wordsTemplate:Ranchor
and emphasizes the primacy of Harlow's three publications as sources.Template:Ranchor
(Harlow's original case notes have not survived.Template:Ranchor
A Warren Museum curator referred to the "stately elegance" of Harlow's writings on Gage.[27])
Macmillan& LenaTemplate:Ranchor present previously unknown sources found since 2008.
^ abcMacmillan gives background on Cavendish (at the time called Duttonsville),
the location and circumstances of the accident, and the steps in setting a blast.Template:RanchorTemplate:RanchorTemplate:Ranchor
The blast hole, about 1+3⁄4 inches (4.5cm) in diameter and up to 12 feet (4m) deep, might require three men working as much as a day to bore using hand tools.
The labor invested in setting each blast, the judgment involved in selecting its location and the quantity of powder to be used, and the often explosive nature of employer-employee relations on this type of job, all underscore the significance of Harlow's statements that Gage has been a "great favorite" with his men, and that his employers had considered him "the most efficient and capable foreman in their employ" prior to the accident.Template:Ranchor
^ ab[15] The Boston Post credits an earlier report (of unknown date) in the Ludlow (Vermont) Free Soil Union, which appears to have been the first report of Gage's accident;Template:Ranchor although reprinted by several New England papersTemplate:Ranchor it is itself no longer extant.Template:Ranchor
This report confuses the iron's circumference with its diameter,Template:Ranchor
and despite the reference to "shattering the upper jaw", that did not in fact happen.[16]
^[12]: 54 Template:Ranchor
"Harlow always refers to the bar by its proper title, as a tamping iron. Bigelow's reference to a crowbar... gave the case its nickname, which is still encountered today." Template:Ranchor
^Williams family lore holds that Harlow did not appear until two days after Gage's accident, but nonetheless "sought eventually to take the whole glory of the successful outcome" of the case, even though Williams "was given full credit by all those who knew of his connection" to it. However, these stories conflict with every other account of Gage, including Williams' own.Template:Ranchor
^In keeping with usage of the day[17]: 107 Harlow used the term fungus (a word possibly related to the Greek word for "sponge"[citation needed]) in reference to the sponge-like granulation tissue.Template:Ranchor
^[14]
In the pre-asepsis era in which Harlow practiced,Template:Ranchor wrote surgeon Frederick Treves,
"Practically all major wounds suppurated. Pus was the most common subject of converse, because it was the most prominent feature in the surgeon's work. It was classified according to degrees of vileness." [18]: 347
But pus of the right kind was considered desirable.[19]: 80
"If a patient was lucky... a thick cream-colored odorless fluid would appear within five or six days";
such "laudable" pus was considered "a sure sign that the wound would heal" [18]: 344
because it meant "Nature has put up a bold fight against the invader".[20]
"On the other hand, if the pus gradually became watery, blood tinged and foul smelling, it was designated 'sanious' [21]
[or 'ill-conditioned' ] [22]
and the wound condition was considered unfavorable".[21]
(It later came to be understood that "laudable" pus generally implied an invasion of relatively benign staphylococci, while "ill-conditioned" pus usually meant the more dangerous streptococcus was present.[18]: 345 [21]: 247 )
^Though "the globe of the left eye was protruded from its orbit by one-half its diameter" by the accident, Gage retained "indistinct" vision in it until the tenth day, when vision was permanently lost.Template:Ranchor
Ratiu etal. conclude that "the optic canal was spared... [the vision loss] secondary to acute glaucoma or swelling of the optic nerve and compression against the rigid walls of the optic canal." Template:Ranchor
Harlow added that Gage could "adduct and depress the globe, but cannot move it in any other direction."
^ abcdGage's death and original burial are discussed by MacmillanTemplate:Ranchor (and see "Corrections to An Odd Kind of Fame").Template:Ranchor
Harlow gives Gage's date of death as May21, 1861,Template:Ranchor
but because bound, consecutive interment records[29]
show that Gage was buried May23, 1860,Template:Ranchor
Macmillan concludes that May21, 1860 is the correct death date;Template:RanchorTemplate:Ranchor
this is confirmed by a contemporary obituary.[30]
(Harlow's informant was Gage's mother;Template:RanchorTemplate:Ranchor MacmillanTemplate:Ranchor points out that, when combined with Gage's age at death, the 1861 date obscures the fact that Gage had been conceived out of wedlock.) This implies that certain other dates Harlow gives for events late in Gage's life—his move from Chile to San Francisco and the onset of his convulsions—are also mistaken, presumably by the same one year; this article follows MacmillanTemplate:Ranchor
in correcting those dates (each of which carries this annotation).
In 1867 Lone Mountain Cemetery was renamed Laurel Hill Cemetery.[31]
^Template:Ranchor Early attempts to estimate the extent of damage include those by: Harlow;Template:Ranchor Edward Elisha Phelps[23]; Bigelow;Template:Ranchor Harlow;Template:Ranchor Dupuy;[36] Ferrier;[37]
Bramwell;[38] Cobb;[39] Tyler& Tyler.Template:Ranchor
^Template:Ranchor Kotowicz continues, "Damasio's account of Gage's last months [is] such a grotesque fabrication that it leaves one baffled," Template:Ranchor then quotes this passage from A.Damasio:[71]: 9-10
In my mind is a picture of 1860s San Francisco as a bustling place, full of adventurous entrepreneurs engaged in mining, farming, and shipping. That is where we can find Gage's mother and sister, the latter married to a prosperous San Francisco merchant (D.D. Shattuck, Esquire), and that is where the old Phineas Gage might have belonged. But that is not where we would find him if we could travel back in time. We would probably find him drinking and brawling in a questionable district, not conversing with the captains of commerce, as astonished as anybody when the fault would slip and the earth would shake threateningly. He had joined the tableau of dispirited people who, as Nathanael West [see The Day of the Locust] would put it decades later, and a few hundred miles to the south, "had come to California to die."
Kotowicz comments: "This little literary flourish is pure invention... There is something callous in insinuating that Gage was some riff-raff who in his final days headed for California to drink and brawl himself to death."
MacmillanTemplate:Ranchor gives detailed criticism of A.Damasio's various presentations of Gage (some of them in joint work with H.Damasio and others).
^In addition to the "attested statements" mentioned by Harlow (which Harlow had gathered at Bigelow's request) and his own examination of Gage, Bigelow pointed out that the accident had occurred "in open day" with many witnesses, and that "in a thickly populated country neighbourhood, to which all the facts were matter of daily disucssion at the time of their occurrence, there is no difference of belief, nor has there been at any time doubt that the iron was actually driven through the brain. A considerable number of medical gentlemen also visited the case at various times to satisfy their incredulity." Template:RanchorTemplate:Ranchor
^
Template:Ranchor
At the very meeting at which Harlow unveiled Gage's skull and iron, Bigelow
("in one of those coup dramatiques which were now and then incidents of his surgical communications [and] without giving notice that he intended to do so" [83]: 123 )
actually produced this patient, Joel Lenn, together with "the gas pipe which had pierced his head from the right forehead to left occiput, and the hat he had been wearing (with entrance and exit holes)... This coup de théâtre must have been a painful coda for Harlow, eclipsing the pinnacle of his medical career." Template:Ranchor
A side effect of Lenn's post-accident medical treatment was to rid him of a 17-foot tapeworm. Months after the accident, his surgeon reported, "He seems to be perfectly rational, and will reply correctly in monosyllables to questions, but is entirely unable to connect words. He succeeds best, when excited, in swearing in French." [84]
