Born 24 Nov 1921; died 3 Jan 1989 at age 67.American chemist who co-discovered crystalline polypropylene polymer, with J. Paul Hogan. They were assigned by Phillips Petroleum, in 1946, to research ways to take the natural gas products propylene and ethylene and turn them into useful gasoline components.
