Brigid Brophy was an English novelist, essayist, critic, biographer, and dramatist. In the Dictionary of Literary Biography: British Novelists since 1960, S. J. Newman described her as "one of the oddest, most brilliant, and most enduring of [the] 1960s symptoms." She was a feminist and pacifist who expressed controversial opinions on marriage, the Vietnam War, religious education in schools, sex (she was openly bisexual, and pornography. She was a vocal campaigner for animal rights and vegetarianism. A 1965 Sunday Times article by Brophy is credited by psychologist Richard D. Ryder with having triggered the formation of the animal rights movement in England.
