Henry Shakespear Stephens Salt (1851-1939) was an English writer and campaigner for social reform in the fields of prisons, schools, economic institutions, and the treatment of animals. He was a noted ethical vegetarian, anti-vivisectionist, socialist, and pacifist, and was well known as a literary critic, biographer, classical scholar and naturalist. It was Salt who first introduced Mohandas Gandhi to the influential works of Henry David Thoreau, and influenced Gandhi’s study of vegetarianism. Salt is considered, by some, to be the “father of animal rights”. An Old Etonian, he returned to teach there for ten years.
