Recent studies of the social history of birth control in America have noted the importance of eugenics in securing the acceptance of family planning between the two world wars. Similarly in England the endorsement of contraception as a method of “race improvement” by eugenists in the scientific, medical, academic and ecclesiastical communities greatly enhanced the credence and respectability of the birth control movement. In the anti-racist, genetically more sophisticated climate since the Second World War it is often forgotten how pervasive eugenic assumptions about human inheritance were in learned and socially elevated circles in the early twentieth century. Belief in the inheritability of myriad physical, psychological and behavioral characteristics, identifiable, even quantifiable, in particular ethnic groups and social classes was reinforced by expert scientific testimony, and, perhaps equally important, middle and upper class prejudices.
Birth control leaders, whose respectability was always in some doubt, were for the most part no exception and readily mingled with the estimable worthies who adorned the ranks of the elitist Eugenics Education Society founded in 1907. Several officers of the old Malthusian League, including its last president, Charles Vickery Drysdale, and his wife, Bessie, were early if troublesome recruits to the Society, while Marie Stopes, the most dynamic promoter of birth control in England in the inter-war years, joined in 1912, and eventually became a Life Fellow who left the organization a financial legacy, her famous clinic and much of her library, upon her death in 1958.
