Single Form

Copies of a smaller version, Single Form (Memorial) (BH 314),[1] are on public display outside the Johns Hopkins University's Paul H. Nitze School of Advanced International Studies in Washington, D.C., and in Battersea Park in London.

In 1970, the art critic Edwin Mullins suggested: "it is a torso, it is a profile with an eye, it is an expanse of space in which the sun rises, it is a blade, it is a human hand ... raised flat in a sign of authority, or of salute, or as a gesture of allegiance".

Another related work is Hepworth's 1961 bronze Curved Form (Bryher II): a similar shape, pierced with a hole, with copper strings; an example was sold at auction at Christie's in 2013.

(The year before, Hepworth had completed Meridian, and was working on Maquette (Three Forms in Echelon) for the John Lewis store on Oxford Street, which became Winged Figure.)

Hepworth doubled the size of Single Form (Memorial) to create a full-size armature at the Palais de Danse annex to her studio in St Ives in early 1963, in wood covered with plaster.

It was erected in New York in May 1964, standing on a granite plinth near the edge of a circular pool of water, about 100 feet (30 m) in diameter, with a fountain, which had been built with a $50,000 gift from the children of the United States, Puerto Rico and the US Virgin Islands; it was unveiled on 11 June 1964.
