DESCRIPTION
Percy Lavon Julian (April 11, 1899 - April 19, 1975) was an American research chemist and a pioneer in the chemical synthesis of medicinal drugs from plants. He was the first to synthesize the natural product physostigmine; and was a pioneer in the industrial large-scale chemical synthesis of the human hormones, steroids, progesterone, and testosterone, from plant sterols such as stigmasterol and sitosterol. His work would lay the foundation for the steroid drug industry's production of cortisone, other corticosteroids, and birth control pills.
