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 progesterone and testosterone from plant sterols such as stigmasterol and sitosterol. His work laid 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 wild Mexican yam. His work helped greatly reduce the cost of steroid intermediates to large multinational pharmaceutical companies, helping to significantly expand the use of several important drugs, including synthesizing cortisone.
He received more than 130 chemical patents. He 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 (after David Blackwell) from any field.
Early life and family
Percy Lavon Julian was born on April 11, 1899, in Montgomery, Alabama, as the first child of six born to James Sumner Julian and Elizabeth Lena Adams Julian. Both of his parents were graduates of what was to be Alabama State University. His father, James, whose own father had been enslaved, was employed as a clerk in the Railway Service of the United States Post Office, and his mother Elizabeth was a schoolteacher.
Education and academic career
At a time when access to an education beyond the eighth grade was extremely rare for African Americans, Julian's parents steered all of their children toward higher education. Julian attended DePauw University in Greencastle, Indiana. The college accepted few African-American students. The segregated nature of the town subjected him to social humiliations. He was not allowed to live in a college dormitory and first stayed in an off-campus boarding home, which refused to serve him meals. It took him days before he found an establishment where he could eat. He later found work firing the furnace, waiting tables, and doing other odd jobs in a fraternity house; in return, he was allowed to sleep in the attic and eat at the house. Julian graduated from DePauw in 1920 as a Phi Beta Kappa and valedictorian.
By 1930, his father had moved the family to Greencastle so that all his children could attend DePauw. He still worked as a railroad postal clerk. James owned his own home, valued at $3,000 (approximately $ today).
After graduating from DePauw, Julian wanted to obtain his doctorate in chemistry, but learned it would be difficult for an African American to do so. Instead, he obtained a position as a chemistry instructor at Fisk University. In 1923 he received an Austin Fellowship in Chemistry, which allowed him to attend Harvard University to obtain his M.S. However, worried that white students would resent being taught by an African American, Harvard withdrew Julian's teaching assistantship, making it impossible for him to complete his Ph.D. there.
In 1929, while an instructor at Howard University, Julian received a Rockefeller Foundation fellowship to continue his graduate work at the University of Vienna, where he earned his Ph.D. in 1931. He studied under Ernst Späth and was considered an impressive student. Europe gave him freedom from the racial prejudices that had stifled him in the States. He freely participated in intellectual social gatherings, attended the opera, and found greater acceptance among his peers. Julian was one of the first African Americans to receive a Ph.D. in chemistry, after St. Elmo Brady and Edward M.A. Chandler.
After returning from Vienna, Julian taught for one year at Howard University. At Howard, in part due to his position as a department head, Julian became caught up in university politics, setting off a chain of scandals. At university president Mordecai Wyatt Johnson's request, he goaded white professor of chemistry Jacob Shohan (Ph.D., Harvard), into resigning. In late May 1932, Shohan retaliated by releasing to the local African-American newspaper the letters Julian had written to him from Vienna. The letters described "a variety of subjects from wine, pretty Viennese women, music and dances, to chemical experiments and plans for the new chemical building." In the letters, he spoke with familiarity, and some derision, of members of the Howard University faculty, calling one well-known dean an "ass (also known as a donkey)".
