Contributions of alumni and friends in 1979 established the Danforth Lectureship, which aims to bring the most significant practitioners of chemistry to Grinnell College. The Lectureship honors a distinguished member of the Chemistry Department, Joseph D. Danforth, who joined the faculty in 1947 and retired in 1979. Professor Danforth was a baccalaureate of Wabash College and received his Ph.D. at Purdue University. He was a research chemist for the Universal Oil Products Co. in Chicago for ten years before joining the Grinnell faculty. Professor Danforth carried on an active research program in heterogeneous catalysis and in kinetics of decomposition of solids while teaching at Grinnell. This work was pursued throughout his career and into his retirement with scores of Grinnell students who are now scientists.
