Florence Gertrude James (2 September 1902 – 25 August 1993) was an Australian author and literary agent.
Born in Gisborne, New Zealand, she moved with her family to Sydney in 1920. Her father was a refrigeration engineer with a successful consulting practice.
She studied at Sydney University from 1923–26 and it was there her friendship with Dymphna Cusack began, later to become a notable collaboration. They were both involved in debating and theatre; they shared a feminist, unionist and pacifist outlook. Both were much later to become opponents of nuclear weapons.
She married lawyer William J 'Pym' Heyting in London in 1932 and had two daughters, Julie and Frances, by him. They returned to Sydney in 1938. He joined the RAAF as an Intelligence officer, and became a Wing Commander.
She worked as Public Appeals Officer for The Royal Prince Alfred Hospital from 1940 to the end of 1944, when she resigned. From 1945 to 1947 she, her daughters, Dymphna Cusack and her niece shared a rented cottage 'Pinegrove' at Hazelbrook in the Blue Mountains. It was there that they collaborated on a children's book Four Winds and a Family and Come In Spinner, which was to become the most successful book about life in wartime Sydney. It won the Daily Telegraph literary prize in 1948. Publishers demanded substantial edits and it was not finally published until 1951.
She returned with her daughters to London in 1947 to join her husband who was stationed there. They divorced in 1948. She remained there until 1963, working as a literary agent, initially for Constable and Company, where authors she signed included Mary Durack, Sylvia Townsend Warner and Colin Johnson (aka Mudrooroo Narogin). She became active in the Campaign for Nuclear Disarmament, participating in the Aldermaston March and activities of Bertrand Russell's Committee of One Hundred.
