Dr. Percy Lavon Julian, son of a railway mail clerk and a schoolteacher, a grandson of slaves, seemed destined for greatness.  Julian exhibited  the positive attributes of courage, tenacity, scholarship, industry, and business keenness--characteristics that molded a pioneer and a role model for future researchers in chemistry.  His research at the Glidden Company resulted in the development of a process to derive cortisone from a base of soybean oil.  Julian's pioneering work with the protein-rich soybean was of enormous use in seeking a solution to the worldwide problem of protein deficiency.
