Henry Stephens Salt

Henry Stephens Salt (20 September 1851 – 19 April 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 Mahatma Gandhi to the influential works of Henry David Thoreau.

Salt is credited with being the first writer to argue explicitly in favour of animal rights, in his Animals' Rights: Considered in Relation to Social Progress (1894), rather than focusing on improvements to animal welfare. He wrote: "If we are ever going to do justice to the lower races, we must get rid of the antiquated notion of a 'great gulf' fixed between them and mankind, and must recognize the common bond of humanity that unites all living beings in one universal brotherhood."
