History and etymology

Williams syndrome was first identified in 1961 by J C P (John Cyprian Phipps ) Williams (1922-fl.1970s), a New Zealander cardiologist, who was a rather eccentric individual. He was last seen alive in the mid 1970s in Salzburg in Austria. Interpol were unable to locate Dr Williams after a request from his sister and in 1988 the High Court of New Zealand decreed that he was “a missing person presumed to be dead from 1978” .
