Eileen Palmer, Olive Johnson, and Edith How-Martyn worked closely together in the British birth control movement during a period from the 1920s to the 1950s. How-Martyn had been active in this cause since before the First World War. They were all involved with the Birth Control International Information Centre and Birth Control Worldwide organisations during the 1930s, and Palmer accompanied How-Martyn on one of her several tours of India to promote birth control. How-Martyn undertook a number of other foreign tours, before emigrating to Australia with her husband around 1940. There is an entry for How-Martyn in the Oxford Dictionary of National Biography, and some obituaries and other biographical material in A.8.
