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 WWI 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.
