Elion graduated from Hunter College (1937) and received a master's degree in chemistry from New York University (1941). She became Hitchings' assistant at Burroughs Wellcome, a drug company, in 1944. Working together for 23 years, they developed drugs to treat herpes, malaria, and immune disorders, and to prevent the rejection of transplanted organs.
