Richard Ryder created the term speciesism in early 1970 and shared the idea with Peter Singer, who popularised it in his classic work _Animal Liberation_. A key figure in the modern animal rights revival Ryder appeared on the first-ever televised discussion of animal rights in December 1970. He further promoted the ideas around speciesism in recorded discussions with Bridget Brophy, for the Open University, and in his contribution to the seminal philosophical work _Animals Men and Morals_ edited by the Oxford philosophers Stanley and Roslind Godlovitch and John Harris in 1971. From 1969 Ryder organised protests against animal experiments and bloodsports. He continued to promote his ideas about speciesism in leaflets and broadcasts, culminating in the publication of his _Victims of Science_ in 1975 - a book that provoked debates in Parliament and on television and was described by _The Spectator_ at the time as "a morally and historically important book". Dr Ryder was elected to the RSPCA Council in 1971, first becoming Chairman in 1977. In 1980 he was founding Chairman of the Liberal Democrat Animal Protection Group, and later ran for Parliament, was Director of the Political Animal Lobby and then Mellon Professor in the Department of Philosophy at Tulane University. Ryder coined the term painism to describe his wider moral theory in 1990. He has several times broadcast on the BBC's Moral Maze.
