Julian, Percy Lavon (1899-1975), a United States chemist. His research during the 1940's made possible the quantity production of testosterone and progesterone (the male and female hormones) and cortisone from soybeans. He also produced soybean extracts that are used to put out fires, to make paint, and to coat paper. Julian, who was born in Montgomery, Alabama, attended DePauw and Harvard universities. He received a Ph.D. degree from the University of Vienna (1931) and taught chemistry at Fisk, DePauw, and Howard universities. He was a director of research for the Glidden Company, 1936-53. He headed Julian Laboratories, Inc., 1953-64, and the Julian Research Institute, 1964-75. In 1947 he was awarded the Spingarn Medal for outstanding achievement by a black American.
He's ventured to the abyss of black holes, wagered on the information paradox and floated around in zero gravity. Meet the man, the legend, the super scientist: Stephen Hawking.
He was born exactly 300 years after Galileo died. He has yet to be awarded a Nobel Prize, although he was awarded a guest spot on “The Simpsons.” What else do you know (or not know) about this acclaimed physicist?
