Roger Adams

Died 6 Jul 1971 at age 82 (born 2 Jan 1889). American organic chemist who joined the faculty at the University of Illinois at Urbana in 1916, which he converted into the leading centre of organic chemistry in the U.S. and forged links with industry, notably with Du Pont. Adams worked out the chemical composition of various natural substances, including chaulmoogra oil (which is used in treating leprosy), gossypol (a toxic cottonseed pigment), marijuana, and many alkaloids. He also worked in stereochemistry and with platinum catalysts and the synthesis of medicinal compounds. His name is associated with chemical warfare agent Adamsite (diphenylamine chloroarsine) and the Adams catalyst (platinum oxide or palladium oxide, used for the hydrogenation of carbon-carbon double bonds).
