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. While at Glidden, his chemical synthesis of human steroids from plant steroid precursors would lay the foundation for the birth control pill and cortisone. After leaving Glidden he started his own company and competed against Syntex, and testified before a US Senate committee to break their monopoly on synthesizing human steroids from the Mexican yam. His competition helped reduce the cost of synthetic steroids.

During his lifetime he received more than 130 chemical patents. Julian was the second African American 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.

Early life and education

Julian was born in Montgomery, Alabama to Elizabeth Lena Adams (1878-?) and James Sumner Julian I (1871-?). James was a railway mail carrier for the United States Post Office, and his father was a slave. Elizabeth worked as a school teacher. He grew up in the time of Jim Crow. Among his childhood memories was finding a lynched man hung from a tree while walking in the woods near his home. While it was generally unheard of for African Americans at the time to pursue an education beyond the 8^th grade, Julian's father steered all of his children towards higher education. Julian attended DePauw University in Greencastle, Indiana. At the time, the college accepted very few African American students and its town was still segregated. Julian was not allowed to live in the college dormitories and initially stayed in an off campus boarding home where he was refused meals. It was days after his arrival before Julian found an establishment that would allow him to eat. Ultimately, he took work firing the furnace and doing other odd jobs in a fraternity house and, in return for his service, he was allowed to sleep in the basement and eat. He graduated from DePauw in 1920 Phi Beta Kappa and valedictorian.. By 1930 Julian's father had moved the entire family to Greencastle, Indiana so that all his children could attend college at Depauw, he was still working as a railroad postal clerk.

Julian wanted to obtain his doctorate in chemistry but learned it would be difficult for an African American. He was denied access to American doctorate programs because they felt that the only jobs obtainable post-graduation would be as instructors at all black colleges. After graduating from DePauw, Julian became a chemistry instructor at Fisk University. He then received an Austin Fellowship in Chemistry and went to Harvard University in 1923 for his M.S. Worried that that white students would resent being taught by an African American, Harvard withdrew Julian's teaching assistantship and he was unable to complete his Ph.D. at Harvard. In 1929 Julian received a Rockefeller Foundation fellowship to continue his graduate work at the University of Vienna, and he received his Ph.D. in 1931. He studied under Ernst Späth and was considered an impressive student. In Europe, he found freedom from the racial prejudices that nearly stifled him in the States. He freely participated in intellectual social gatherings, went to the opera and found greater acceptance among his peers. Julian was the second African American to receive a Ph.D. in chemistry after St. Elmo Brady.

Physostigmine

After returning from Vienna, he went to Howard University for one year, where met his future wife, Anna Roselle Johnson (Ph.D. in Sociology, 1937, University of Pennsylvania). They married on December 24, 1935 and had two children: Percy Lavon Julian, Jr. (1940- ), a lawyer in Madison, Wisconsin; and Faith Roselle Julian (1944- ).At Howard, Julian got involved in university politics, he goaded a white chemist named Jacob Shohan into resigning. Shohan retaliated by releasing to the local African American newspaper the letters Julian had written to him from Vienna. The letters contained accounts of his sex life, and criticism of individual Howard faculty members. Julian's laboratory assistant, Robert Thompson, also charged he had found his wife and Julian together in a sexual tryst. When Thompson was fired for filing a lawsuit against the University, he released the letters that Julian had written to him from Vienna just as Shohan had. Through the summer of 1932, the Baltimore Afro-American published all of Julian's letters.

William Blanchard then offered him a position to teach organic chemistry at DePauw University in 1932. Julian helped Josef Pikl, a fellow student at the University of Vienna, to come to the United States to work with him at Depauw. In 1935 Julian and Pikl completed the total synthesis of physostigmine, and confirmed the structural formula assigned to it. Robert Robinson of Oxford University was the first to publish a synthesis of physostigmine, but Julian noticed that the melting point was wrong for Robinson's end product. When Julian completed his synthesis, the melting point matched the correct one for natural physostigmine from the calabar bean.

Julian also at this time extracted from Calabar beans, stigmasterol that reportedly could serve as raw materials for synthesis of male and female hormones.

Glidden

After being denied a professorship at DePauw in 1936 for racial reasons, Julian applied for a job at the Institute of Paper Chemistry (IPC) in Wisconsin. However, the Wisconsin city of Appleton where the institute was located, had a law forbidding African Americans from staying overnight. DuPont had offered a job to fellow chemist Josef Pikl, but declined to hire Julian, who had superlative qualifications as an organic chemist, apologizing that they were "unaware he was a Negro".

W.J. O'Brien, a vice-president at the The Glidden Company, a Cleveland, Ohio paint company, and board member of IPC, Appleton, offered Julian the position of director of research at their newly created Soya Products Division in Chicago, Illinois.[1] He was very likely offered the job by O'Brien because he was fluent in German and Glidden had just purchased a modern continuous countercurrent solvent extraction plant from Germany for the extraction of "vegetable" oil from soybeans for paints and other uses*Bernhard Witkop memoir of Julian

Julian supervised the assembly of the plant at Glidden when he arrived in 1936. He then designed and supervised construction of the world's first plant for the production of industrial-grade, isolated soy protein from oil-free soybean meal. Isolated soy protein could replace the more expensive milk casein in industrial applications such as coating and sizing of paper, and in the manufacture of paints. Just prior to World War II, Julian discovered that upon hydrolysis, soy protein could be used as a fire-extinguisher when converted into a foam by means of an aerating nozzle. It could smother oil and gasoline fires on board ships, before the flames could engulf the ship. This invention saved the lives of thousands of American sailors.

Julian's research at Glidden changed in 1940 when he began work on synthesizing progesterone and testosterone from the plant sterol stigmasterol, isolated from soybean oil. His work made possible the production of these hormones on a large (kilogram) industrial scale, reducing the cost of treating hormonal deficiencies. Julian and his co-workers obtained patents for Glidden on key processes for the preparation of sex hormones from soybeans. In 1947, the NAACP awarded him the Spingarn Medal, its highest honour. In 1949 the importance of cortisone for treatment of rheumatoid arthritis motivated pharmaceutical firms to synthesize cortisone and its analogs from animal bile acid starting materials. Julian undertook its synthesis from pregnenolone, available from soybean oil sterols, devising a series of processes to convert pregnenolone to cortexolone which differs from cortisone only in lacking an oxygen atom at the C-11 position. The industrial production of cortisone became possible in 1952 when the Upjohn Company announced that oxygenation at C-11 could be achieved in high yield by microbial oxidation. This made intermediates such as cortexolone, progesterone, and pregnenolone valuable in the production of a variety of corticoid drugs.

Oak Park

Around 1950 Julian moved his family from Chicago to the suburb of Oak Park, Illinois, where the Julians were the first African American family. Although some residents welcomed them into the community, there was also widespread antipathy towards them. Their home was fire-bombed on Thanksgiving Day, 1950, before they moved in. After they moved to Oak Park, the house was attacked with dynamite on June 12, 1951. The attacks galvanized the community and a community group was formed to support the Julians. Julian's son later recounted that during these times, he and his father often kept watch over the family's property by sitting in a tree with a shotgun.

In 1953, he founded his own research firm, Julian Laboratories, Inc. He brought many of his best chemists including African Americans and women from Glidden to his own company. He won a contract to provide Upjohn with $2 million worth of progesterone. To compete against Syntex he would have to use the same Mexican yam as his starting material. He borrowed and used his own money to build a processing plant in Mexico, but could not get a permit to harvest the yams from the government. Abraham Zlotnik found a new source of the yam in Guatemala for the company, and Julian appeared before the U.S. Senate in 1956 and testified that Syntex was using undue influence to monopolize access to the Mexican yam. Julian was able to reduce the cost of the steroid they produced from $4,000 a kilogram down to about $400 a kilogram.

He sold the company in 1961, for $2 million dollars. The U.S. and Mexico facilities were purchased by Smith Kline and his chemical plant in Guatemala was purchased by Upjohn. In 1964, he founded Julian Associates and Julian Research Institute, which he managed for the rest of his life.

National Academy of Sciences

He was elected to the National Academy of Sciences in 1973 in recognition of his scientific achievements. He was the second African American after David Blackwell.

Death

Julian died of cancer on April 19, 1975 in St. Theresa's Hospital in Waukegan, Illinois and was buried in Elm Lawn Cemetery in Elmhurst, Illinois.
