Huxley was born in London, the eldest son of George Hamborough and Lilian Huxley. He was a second-cousin once removed of Thomas Huxley. His family migrated from England to Australia in 1905 when he was three, and settled in Tasmania, where Huxley showed great academic and sporting promise while attending The Hutchins School. He won a Rhodes Scholarship to New College, Oxford while in his second year at the University of Tasmania and obtained a D.Phil. from Oxford in 1928. On 5 October 1929 he married Ella Mary Child 'Molly' Copeland who was reading history at Somerville College.
