Ysabel Hunter née Birkbeck (16 June, 1890–1973) was a British ambulance driver and war memoirist. Her parents were Henry Birkbeck, a London-born banker, and Ysabel Birkbeck (née Elwes), a toymaker and philanthropist. Ysabel had a privileged upbringing, which she rejected in favour of art and wartime service during both the First and Second World Wars.
