G. Raymond Rettew
A West Chester chemist, he pioneered the mass production of penicillin, the world's first antibiotic. In 1943, with Wyeth Laboratories, his lab (a converted auto repair shop here) made & sent more penicillin to the Armed Forces than any other lab in the world, saving countless lives on the battlefields of World War II.
