Percy Lavon Julian was the first scientist to chemically synthesise the drug physostigmine and pioneered the large-scale production of the human hormones progesterone and testosterone.

His work in the chemical synthesis of hormones led to the development of other important drugs such as the contraceptive pill.

Julian founded his own company, Julian Laboratories, where he synthesised steroids from Mexican yam.

His research reduced the cost of steroids to drugs companies and helped expand the use of important drugs.

Percy Lavon Julian overcame challenges to become one of the first African Americans to receive a chemistry doctorate and he was the first African American chemist to become a member of the National Academy of Sciences.
