A lead advocate of medical research in Canada, Dr. Johnson MacLeod graduated from Dalhousie University in 1937, but had difficulty finding a residency. Dr. Harold Griffith, the inaugural president of the Canadian Anaesthetists’ Society when it re-formed in 1943, gave her the opportunity.
Dr. Johnson Macleod and Dr. Griffith’s work was key in the development of the curare muscle relaxant in 1942. She was an active member of the Federation of Medical Women in Canada (FMWC) and was its president in 1969-70. The FMWC’s Enid Johnson MacLeod Annual Award is given to an advocate of women’s health research and women’s health education.
