Cyril Clarke and the prevention of rhesus haemolytic disease of the newborn.

Cyril Clarke was an outstanding general physician and lepidopterist. Late in his career, and stimulated by his work on the genetics of mimicry in butterflies, he became interested in the evolving field of medical genetics. His work on the relationship of blood groups to particular diseases led him and his team in Liverpool to evolve a remarkably successful approach to the prevention of Rhesus haemolytic disease of the newborn.
