Daniel Charles Drucker (June 3, 1918 – September 1, 2001) was American civil and mechanical engineer and academic, who served 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.
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 in New York City. His father Moses Abraham Drucker was a civil engineer, and Drucker wanted to follow in his footsteps.
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.
Career, honours and awards
Drucker taught at Brown University from 1946 until 1968 when he joined the University of Illinois as Dean of Engineering. In 1984 he left Illinois to become a graduate research professor at the University of Florida until his retirement in 1994.
In 1988, Drucker was awarded the National Medal of Science. He was a member of the National Academy of Engineering and of the American Academy of Arts and Sciences. The Drucker Medal is named in his honor. He was also awarded the Timoshenko Medal in 1983.
He died from leukemia on September 1, 2001.
