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. He later started his own company to synthesize steroid intermediates from the Mexican wild yam. His work helped reduce the cost of steroid intermediates to large multinational pharmaceutical companies.
During his lifetime he received more than 130 chemical patents. Julian was one of the first African Americans to receive a doctorate in chemistry. He was the first African-American chemist inducted into the National Academy of Sciences, and the second African-American scientist inducted from any field.

Famous quotes containing the word julian:
“The rich were dull and they drank too much or they played too much backgammon. They were dull and they were repetitious. He remembered poor Julian and his romantic awe of them and how he had started a story once that began, The very rich are different from you and me. And how someone had said to Julian, Yes, they have more money.”
—Ernest Hemingway (18991961)
