Jill Phipps (15 January 1964 — 1 February 1995) was a British animal rights activist who was crushed to death in Baginton, Warwickshire, England by a lorry transporting live veal calves heading for continental Europe via Coventry Airport.

Phipps did well at school but chose not to stay on after the age of 16; she went to work for the Royal Mail (her father was a postman). She had become interested in caring for animals when young, and joined her mother's campaigning against the fur trade from the age of 11. After herself becoming a vegetarian, Phipps persuaded the rest of her family to join them. By her late teens she joined the Eastern Animal Liberation League, a group affiliated to the Animal Liberation Front. A local campaign in Coventry supported by Phipps and her mother succeeded in closing down a local fur shop and fur farm. In 1986, together with her mother and sister, Phipps raided the Port Sunlight factory of soap manufacturers Unilever to protest at their use of animal testing. After smashing computer equipment, the group were caught and prosecuted, with Phipps' mother being sentenced to six months' imprisonment and her sister to eighteen months. Phipps herself received a suspended sentence as she was pregnant.

Shannon Keith is an American animal rights lawyer, activist, and documentary director/producer. She is the director of the Animal Liberation Front documentary, Behind the Mask: The Story Of The People Who Risk Everything To Save Animals.

Keith grew up in Los Angeles, California, with a house full of animals. Ever since she was a small child, Shannon rescued injured and homeless animals and nursed them back to health or placed them in loving homes.

In later life, Keith became an animal rights activist, documentary film maker and animal rights lawyer. Animals are considered property, and she has striven to change that fact while defending animal rights activists in the courtroom, saving dogs condemned to death in Los Angeles, as well as litigating against those who abuse animals.

Keith has represented a number of well-known animal-rights activists and campaigns, including Stop Huntingdon Animal Cruelty (SHAC) and Kevin Kjonaas, the former president of SHAC USA, against Huntingdon Life Sciences, and the Sea Shepherd Conservation Society.

Barry Horne (17 March 1952 – 5 November 2001) was an English animal rights activist. He became known around the world in December 1998, when he engaged in a 68-day hunger strike in an effort to persuade the British government to hold a public inquiry into animal testing, something the Labour Party had said it would do before it came to power in 1997. The hunger strike took place while Horne was serving an 18-year sentence for planting incendiary devices in stores that sold fur coats and leather products, the longest sentence handed down to any animal rights activist by a British court.

The hunger strike left Horne with kidney damage and failing eyesight, but it was neither the first nor the last he embarked upon, and when he died of liver failure three years later, he had not eaten for 15 days. Media reaction to his death in the UK was hostile, where he was widely described as a terrorist by journalists and politicians. He is viewed as a martyr within the animal rights movement.

Horne was born in Liverpool. His father was a postman, and his mother died when he was very young. He left school at 15, and took a series of jobs as a road sweeper and dustman.
