Cicely Hamilton (1872–1952) was an Anglo-Irish actress, author, and feminist campaigner best known for her 1909 treatise Marriage as a Trade. Her prewar plays include Diana of Dobson’s (1908) and How the Vote Was Won (1909). After working in the north of France during World War I and witnessing how its violence affected civilians, she was inspired to write Theodore Savage (1922), a proto-sf novel presciently foregrounding modern warfare’s destructive power.
