Carlos Blacker

Carlos Paton ('C.P.') Blacker MC FRCP (8 December 1895 – 21 April 1975) was an eminent war hero, psychiatrist and eugenicist who worked with R.A. Fisher and Lionel Penrose.

He was educated at Eton and Oxford where he attained distinction in biology under the tutelage of Julian Huxley. In France he was decorated for gallantry in the Coldstream Guards during World War I but he lost a brother there. However he held that war was dysgenic because it killed people who tended to be above the physical average and deterred thoughtful people from parenthood. He was deeply shaken by his war experience and in coming to terms with it acknowledged a debt to Freud’s writings which stimulated in him an interest in psychiatry.

Qualifying in medicine in 1925 Blacker became a registrar in Guy’s Hospital’s psychiatric department for three years and continued his study at the Maudsley Hospital. He later became a part-time member of its teaching staff and was later the first chairman of the newly established Simon Population Trust.

From 1931 to 1952 Blacker was secretary of the Eugenics Society and he gave it a new focus on birth control and population planning. . His appointment as Secretary was "not without some misgivings of [Leonard] Darwin, its chairman. The differences in outlook, aspirations and in judgement of these two men during their partnership in office in the Eugenics Society led to tensions which have been ably traced by Richard Soloway. Two prominent issues here were Darwin’s reluctance to endorse Blacker’s deep-rooted conviction that research and provision of contraception should be a major feature in the Eugenic Society’s strategy to reduce the fecundity of the lower, less able classes and his disagreement with Blacker’s aspiration to redirect more of the Eugenic Society’s effort from education and propaganda to research and promotion of contraception."
