lie down, [and] stretch its limbs.” As well, Brophy's article was discovered in or around 1969 by a group of postgraduate philosophy students at the University of Oxford, Roslind and Stanley Godlovitch (wife and husband from Canada), John Harris, and David Wood, now known as the Oxford Group. They decided to put together a symposium to discuss the theory of animal rights. Around the same time, the British writer Richard D. Ryder wrote several letters to The Daily Telegraph criticizing animal experimentation; these letters were seen by Brophy, who put Ryder in touch with the Godlovitches and Harris. Harrison, Brophy, and Ryder subsequently became contributors to the Godlovitches' symposium, which was published in 1971 as Animals, Men and Morals: An Inquiry into the Maltreatment of Non-humans (edited by Roslind and Stanley Godlovitch and John Harris). In the mid-1960s, English former model Celia Hammond gained publicity for her trap-neuter-return work "at a time when euthanasia of feral cats was considered the only option." Hammond "fought many battles with local authorities, hospitals, environmental health departments" but stated that she succeeded over the years in showing that control "could be achieved by neutering and not killing." In 1986 she founded the Celia Hammond Animal Trust with the aim of opening a low-cost neutering clinic to control the feral animal population. The first of these clinics opened in Lewisham in 1995, and a second opened in Canning Town in 1999. The Celia Hammond Animal Trust also runs a sanctuary in Brede, East Sussex, for animals which need new homes. In addition to neutering animals, the clinics (and sanctuary) also help to rescue and rehome animals, and now find homes for thousands of cats each year. In 1973 Dr. Shirley McGreal founded the International Primate Protection League in Thailand. In 1980 the English-born British/American animal rights activist Ingrid Newkirk co-founded People for the Ethical Treatment of Animals. Also in 1980 was the first Action for Life conference for animal rights, which was attended by a number of pioneers in the animal rights movement, including Ingrid Newkirk. In 1981 Feminists for Animal Rights was founded in California; it became a nationwide organization in the following years and was active nationwide for over two decades, but is now defunct. In the same year, Priscilla Cohn published Etica aplicada ("Applied Ethics"), written with José Ferrater Mora, containing the first essay on animal rights published in Spain. In 1984
