Katherine Laird ("Ka") Cox (1887–1938), the daughter of a British socialist stockbroker and his wife, was a Fabian and graduate of Cambridge University. There, she met Rupert Brooke, becoming his lover, and was a member of his Neo-Pagans. She was also a friend of Virginia Woolf and the Bloomsbury Group. During World War I she worked with the Serbian Relief Fund, assisting refugees in Corsica. After the war, she married the Labour politician Will Arnold-Forster, and became the first woman magistrate in Cornwall. She and her husband were instrumental in founding Gordonstoun School in Scotland in 1934. Her sudden death at the age of 51 fueled speculation of involvement in the occult.
