Nationality: Why Americans are famous: Percy Lavon Julian has an outstanding career as a chemist, and is a leading figure in plant synthetic drugs in the 20th century. He was the first African-American chemist elected to the National Academy of Sciences. As an African-American, Julian struggled against prejudice all his life. Harvard University did not allow him to pursue a doctorate, and rejected his professorship in depauw university on the grounds of race. 1935, Julian became the first person in Dubois University to synthesize physostigmine, which can be used to treat glaucoma. From 65438 to 0936, Julian worked as the research director in Greden Company, where he successfully obtained many patents and products, including a flame-retardant foam for gasoline combustion, which saved many lives during World War II. Julian also greatly improved the production process of cortisone, so it can be used to treat rheumatoid arthritis more widely. 1953, Julian founded the successful Julian laboratory alone, and later founded the Julian Institute. In order to commemorate Julian's scientific achievements and advocate human rights, some schools in Chicago were named after Julian and issued an American stamp at 1993.
