Baron Cornelius Ver Heyden de Lancey (1889-1984) was a wealthy and public-spirited Dutchman who at different times in his life was a dentist, doctor, surgeon, barrister and art historian. In 1970 he created the De Lancey and De La Hanty Foundation, to promote studies in medico-legal topics. The Foundation generously gave Cambridge the Ver Heyden de Lancey Fund, which since 1996 has funded occasional public lectures on medico-legal issues of current interest.
