Title
Correspondence and publications regarding the commission ‘Single Form’ for the United Nations
Date
25 December 1956–25 October 1973
Description
'Single Form' is Barbara Hepworth's largest work at 21 feet high, and her most significant commission. Hepworth was friends with the second United Nations (UN) Secretary-General Dag Hammarskjöld, he admired her work and borrowed several sculptures for his office in the UN building. Hammarskjöld was killed in a plane crash in Africa in 1961. The Jacob and Hilda Blaustein Foundation then commissioned Hepworth to create a sculpture in his memory, and she designed 'Single Form' (based on a smaller work of the same name made in 1961). The sculpture was unveiled in June 1964 outside the UN headquarters in New York.
There is a large amount of correspondence regarding the commission from the UN, with the Jacob and Hilda Blaustein Foundation, and with the Morris Singer Foundry who cast the sculpture. There are some publications concerning the unveiling ceremony, plans of the work, and photographs of 'Single Form'.
