Donald Vaughan Sinclair (22 April 1911 – 28 June 1995) was a British veterinary surgeon who graduated from the Royal (Dick) School of Veterinary Studies in 1933. He was made famous as the inspiration for the eccentric character Siegfried Farnon, in the semi-autobiographical books of James Herriot (Alf Wight), adapted for film and television as All Creatures Great and Small.
In 1939, Sinclair bought a veterinary practice at 23 Kirkgate, Thirsk, Yorkshire. In July 1940, Sinclair began war service in the Royal Air Force, and hired Alf Wight to run the practice. However, in order to join up, Sinclair had claimed to be younger than he actually was. It was quickly discovered that his reflexes were not fast enough for him to continue with pilot training. He could have been redeployed within the service, but the fact that he was a veterinary surgeon meant that he was considered to be more useful to the war effort by resuming his peacetime profession. The severe national food shortage meant that proper veterinary treatment of farm animals received a high priority and so, within four months of joining the RAF, Sinclair received a compulsory discharge and returned to Thirsk.
Articles about Alf Wight shed more light on the start of the relationship between the two vets. When Sinclair was about to leave for RAF training, he gave Wight all the income of the practice, in return for looking after it during his absence.[1] His brother, Brian Sinclair (Tristan in the books), was not then qualified.
After Sinclair was discharged from the RAF, he asked Wight to stay permanently with the practice, offering a salaried partnership, which Wight accepted.[2]
The fictional Siegfried Farnon is outspoken, opinionated, bossy, quick to lose his temper, and also quick to calm down. He is good-hearted and an animal lover, fond of riding, and infuriated by any suspicion of cruelty to animals. A theme in Herriot's stories was Siegfried's criticism of James's flaws, such as forgetting appointments or leaving instruments behind after calls, only for the reader to find that Siegfried is guilty of the same things. Siegfried also is forgetful, frequently telling people things and then forgetting them within the same day, refusing to believe that when told.
After Wight's first book was published, Sinclair was offended by his portrayal and said, "Alfred, this book is a real test of our friendship". (He never called Wight "Alf", mirrored in the books by Siegfried always referring to Herriot as "James" rather than "Jim".) One of the things he was unhappy about was the name Siegfried, a German name with Wagnerian echoes which, in the 1930s, would have stirred thoughts of Nazis. "Sinclair was so peeved by Wight’s portrayal that at one point he threatened to sue him".[3] Things calmed down and the pair continued to work together until they retired.
Robert Hardy, who played the role of Siegfried Farnon in the BBC Television series, visited Sinclair before playing him, and developed the character based upon his observations. Hardy reminisced that Sinclair hated the way that Hardy played him, and that, Hardy claimed, Sinclair was wholly unaware of his own eccentricities.[4] They subsequently became friends, Sinclair forgiving Hardy. Hardy has said: "I always wished I'd known him before ... It would have helped me to perfect a much more interesting character."[5]
Alf Wight's son, Jim, wrote in his book, The Real James Herriot, that Sinclair's character in the novels was considerably toned down, and that Sinclair was even more eccentric than the Herriot books portrayed.[6][7]
In an interview in 2017, Jim Wight said that "One of the misconceptions [about Alf Wight] was that Sinclair ... was a tyrant and my father was a wimp. Because my father worked harder than Sinclair did, that is absolutely true ... But ... he supported Donald in many ways but he also earned more than Donald. He said to Donald, 'Look, I’m doing all the work. Everything that I do goes into my pocket and everything you do goes into yours.' That’s fair enough, isn’t it?"[6]
Sinclair killed himself with an overdose of barbiturates[8] on 28 June 1995 at his home Southwoods Hall, near Thirsk, two weeks after the death of his wife Audrey (née Adamson), to whom he had been married for 53 years. His brother Brian (Tristan in the books) had died in 1988, and his friend and partner, Alf Wight, only four months previously, in 1995.
Sinclair was survived by a daughter, Jan, and a son, Alan.[5]
