Charles Herbert Fox (1861 – 1939) was a British socialist activist and dentist. Born in Gloucester, the son of a dentist, Fox studied at Sidcot School. His father died when he was fifteen, and he worked as a building supplies manufacturer. However, his health broke down when he was twenty, and the co-operative advocate Samuel Saunders helped him recuperate with gentle work on a smallholding. This led Fox to support the Whiteway Colony, and also to become a vegetarian. Fox stood again for Labour at the 1931 general election, this time in Gloucester, but was again unsuccessful. He died in 1939.
