Frances Ames, South African neurologist, psychiatrist, and human rights activist (d. 2002)
Frances Rix Ames (; 20 April 1920 – 11 November 2002) was a South African neurologist, psychiatrist, and human rights activist, best known for leading the medical ethics inquiry into the death of anti-apartheid activist Steve Biko, who died from medical neglect after being tortured in police custody. When the South African Medical and Dental Council (SAMDC) declined to discipline the chief district surgeon and his assistant who treated Biko, Ames and a group of five academics and physicians raised funds and fought an eight-year legal battle against the medical establishment. Ames risked her personal safety and academic career in her pursuit of justice, taking the dispute to the South African Supreme Court, where she eventually won the case in 1985.

Born in Pretoria and raised in poverty in Cape Town, Ames became the first woman to receive a Doctor of Medicine degree from the University of Cape Town in 1964. Ames studied the effects of cannabis on the brain and published several articles on the subject. Seeing the therapeutic benefits of cannabis on patients in her own hospital, she became an early proponent of legalization for medicinal use. She headed the neurology department at Groote Schuur Hospital before retiring in 1985, but continued to lecture at Valkenberg and Alexandra Hospital. After apartheid was dismantled in 1994, Ames testified at the Truth and Reconciliation Commission about her work on the "Biko doctors" medical ethics inquiry. In 1999, Nelson Mandela awarded Ames the Star of South Africa, the country's highest civilian award, in recognition of her work on behalf of human rights.
