Single Form Single Form Single Form (BH 325) is a monumental bronze sculpture by the British artist Barbara Hepworth. It is her largest work, and one of her most prominent public commissions, displayed since 1964 in a circular water feature that forms a traffic island at the Headquarters of the United Nations in New York City, outside the United Nations Secretariat Building and the Dag Hammarskjöld Library. It is also the largest artwork cast by the Morris Singer foundry. Copies of a smaller version, Single Form (Memorial) (BH 314), are on public display outside the Johns Hopkins University's Paul H. Nitze School
United Nations Operation in the Congo Lumumba wrote to UN Secretary General Dag Hammarskjöld, that from the text of United Nations Security Council Resolution 143 "it is clear that, contrary to your personal interpretation, the UN force may be used to subdue the rebel government of Katanga." Secretary General Hammarskjöld refused. To Hammarskjöld, the secession of Katanga was an internal Congolese matter and the UN was forbidden to intervene by Article 2 of the United Nations Charter. Disagreements over what the UN force could and could not do continued throughout its deployment. In response, Lumumba accused the UN of siding with Tshombe and foreign mining companies.
