The Medical Recording Service Foundation, better known by its later title Graves Medical Audiovisual Library, was founded by husband and wife team Drs John and Valerie Graves in 1957 as an educational activity of the College of General Practitioners (from 1972 the Royal College of General Practitioners). It soon became the premier organisation supplying audiovisual materials for all the medical and paramedical professions in the U.K. Initially it was mainly associated with tape-slide programmes, but by the mid-1980s video programmes also became a major medium.
