title: Sir Cyril Astley Clark, C.B.E., 22 August 1907 - 21 November 2000.
abstract: Cyril Clarke was an outstanding physician, medical scientist and lepidopterist. His career was unusual in that he developed a serious interest in medical research only after many years in clinical practice, a change of direction from the life of a busy consultant physician that was undoubtedly stimulated by his lifelong interest in butterflies. This remarkable transition was to result in his leading the team in Liverpool that developed a method for preventing rhesus haemolytic disease of the newborn, one of the major advances in preventative medicine of the second half of the twentieth century.
