Career

Margaret Jennings joined the University of Oxford's Sir William Dunn School of Pathology under Howard Florey in 1936.[2] By 1938, she was part of the team led by Florey investigating the production and applications of penicillin. Jennings undertook animal work as well as research on bacteriology.[3] As part of testing, Jennings assayed the toxicity of penicillin extracts against white cells of the blood.[4]

Personal life

Margaret married Denys Arthur Jennings in 1930, but the couple divorced in 1946.[1] After 21 years, Jennings married Howard Florey, her long-time colleague and penicillin researcher, in 1967 after the death of his first wife Mary Ethel Florey.[5]
