James J. Stoker

Hailing from Pittsburgh, Pennsylvania, Stoker started his career as a mining engineer. In the 1930s, he went to Zürich to pursue a doctorate in mechanics at the Federal Institute of Technology in Zürich. One of the first courses he took there was by Heinz Hopf on geometry. Stoker was so impressed by the subject, and the teacher, that he switched his doctoral programme to differential geometry He received his Ph.D. degree under the supervision of Hopf and George Pólya. Hopf later recommended Stoker to Richard Courant. In 1937 Stoker, along with Courant's former student Kurt O. Friedrichs, joined Courant in the Department of Mathematics at the New York University. With Stoker's engineering background and Friedrichs' mastery in mathematics, the two were effectively collaborated on many applied problems such as plate theory. On Courant's retirement in 1958 Stoker succeeded him as director and served until 1966. It was during Stoker's period as director, the Institute acquired greater autonomy within the University framework. It became the Courant Institute of Mathematical Sciences in 1965. Friedrichs succeeded Stoker as director in 1966. ==Honors and awards==

• The American Mathematical Society selected Stoker as the Josiah Willards Gibbs lecturer for 1961. • In 1970, Stoker received the Timoshenko Medal in recognition of distinguished contributions to the field of applied mechanics. ==Books==
