The Cornelius Ver Heyden de Lancey
collection comprises manuscript correspondence and documents by over 75 painters, sculptors,
architects, and printmakers, predominantly from 17th- and 18th-century France.
Dutch-born British baron Cornelius Ver Heyden de Lancey (1889-1984) was a medical doctor,
dentist, and barrister, as well as an art historian and collector of French historical
books, letters, and manuscripts. De Lancey studied medicine and dentistry at the University
of Leiden, earned his dental degree in the United States, and practiced dentistry in London
and Italy, where he developed his research interests in art history and the arts. In 1970,
De Lancey and his wife, Josephine de la Hanty, founded the De Lancey and De La Hanty
Foundation, an organization dedicated to the study of medical law that also sponsors arts
initiatives in the Netherlands, the United Kingdom, and France. De Lancey died on Jersey in
the Channel Islands in 1984.
