Percy Julian - Historical records and family trees

In 1929 Julian traveled to the University of Vienna, Austria, to begin doctoral studies on the chemistry of medicinal plants. Two years later, with degree in hand, he and a Viennese colleague, Josef Pikl, took positions back in the United States at Howard and two years later moved to DePauw. There they accomplished the first total synthesis of phys...

Meanwhile researchers in many countries were seeking innovative and cost-effective ways to synthesize steroids, including cortisone and the sex hormones. German chemists discovered that the steroid stigmasterol, which Julian had obtained as a by-product of the physostigmine synthesis but was also obtainable from soybeans, could be used in the synth...

In 1948 scientists at the Mayo Clinic announced their landmark discovery of cortisone, which had remarkable effects on rheumatoid arthritis, and Julian jumped into the exciting competition to synthesize cortisone inexpensively (see also Carl Djerassi). Cortisone is a cortical hormone of the adrenal gland. In 1949 Julian developed a new synthesis fo...

Percy Lavon Julian was born April 11, 1899, in Montgomery, Alabama, the grandson of former slaves. He attended school through the eighth grade but there were no high schools open to Black students. He applied to DePauw University in Greencastle, Indiana, where he had to take high school-level classes in the evening to get him up to the academic lev...

After college, Julian accepted a position as a chemistry instructor at Fisk University. He left in 1923 when he received a scholarship to attend Harvard University to finish his master’s degree, though the university would not allow him to pursue his doctorate. He traveled for several years, teaching at Black colleges, before obtaining his Ph.D. at...

Desiring to leave academia, Julian applied for jobs at prominent chemical companies but was repeatedly rejected when hiring managers discovered that he was Black. Ultimately, he obtained a position at Glidden Company as the lab director. There he invented Aero-Foam, a product that uses soy protein to put out oil and gas fires and was widely used in...
