Daniel Charles Drucker (June 3, 1918 – September 1, 2001) was American civil and mechanical engineer and academic, who served as president of the Society for Experimental Stress Analysis (now Society for Experimental Mechanics) in 1960–1961,[1] as president of the American Society of Mechanical Engineers in the year 1973–74, and as president of the American Academy of Mechanics in 1981–82.[2]

Drucker was known as an authority on the theory of plasticity in the field of applied mechanics. His key contributions to the field of plasticity include the concept of material stability described by the Drucker stability postulates and the Drucker–Prager yield criterion.


Youth and education

Drucker was born in New York City. His father Moses Abraham Drucker was a civil engineer, and Drucker wanted to follow in his footsteps.[3]

Drucker studied at the Columbia University, where he obtained his BSc in civil engineering in 1938. Next, in 1940 he obtained his PhD in mechanical engineering under Raymond D. Mindlin.[3]

Career, honours and awards

Drucker taught at Brown University from 1946 until 1968 when he joined the University of Illinois as Dean of Engineering.[4] In 1984 he left Illinois to become a graduate research professor at the University of Florida until his retirement in 1994.

He received the Murray Lecture and Award in 1967,[5] title the seventh Honorary Member in 1969,[6] Frocht Award in 1971[7] and title of Fellow[8] from the Society for Strain Analysis (SESA), now known as the Society for Experimental Mechanics (SEM). In 1988, Drucker was awarded the National Medal of Science.[9] He was a member of the National Academy of Engineering[10] and of the American Academy of Arts and Sciences. The Drucker Medal is named in his honor.[11] He was also awarded the Timoshenko Medal in 1983.

Daniel C. Drucker Medal

Main article: Drucker Medal

The Daniel C. Drucker Medal, awarded by the American Society of Mechanical Engineers, was named in his honor in 1998. [12] Drucker was the first recipient of this annual award.


Drucker died from leukemia on September 1, 2001.[14]
