synthesized physostigmine for treatment of glaucoma and
cortisone for the treatment of rheumatoid arthritis. Percy
Julian is also noted for a
fire-extinguishing foam for gasoline and oil fires.
Born in Montgomery, Alabama and one of six children, Percy Julian had little schooling. At that time, Montgomery provided limited public education for Blacks. However, Percy Julian entered DePauw University as a "sub-freshman" and graduated in 1920 as class valedictorian. Percy Julian then taught chemistry at Fisk University, and in 1923, earned a master’s degree from Harvard University. In 1931, Percy Julian received his Ph.D. from the University of Vienna.
Percy Julian returned to DePauw University, where his reputation was established in 1935 by synthesizing physostigmine from the calabar bean. Percy Julian went on to become director of research at the Glidden Company, a paint and varnish manufacturer. He developed a process for isolating and preparing soy bean protein, which could be used to coat and size paper, to create cold water paints, and to size textiles. During World War II, Percy Julian used a soy protein to produce AeroFoam, which suffocates gasoline and oil fires.
Percy Julian was noted most for his synthesis of cortisone from soy beans, used in treating rheumatoid arthritis and other inflammatory conditions. His synthesis reduced the price of cortisone. Percy Julian was inducted into the National Inventors Hall of Fame in 1990.
Dr. Percy Lavon Julian was born on April 11, 1899, and died on April l9, 1975.
