Separation from the British Museum

Even after the opening, the Natural History Museum legally remained a department of the British Museum with the formal name British Museum (Natural History), usually abbreviated in the scientific literature as B.M.(N.H.). A petition to the Chancellor of the Exchequer was made in 1866, signed by the heads of the Royal, Linnean and Zoological societies as well as naturalists including Darwin, Wallace and Huxley, asking that the museum gain independence from the board of the British Museum, and heated discussions on the matter continued for nearly one hundred years. Finally, with the passing of the British Museum Act 1963, the British Museum (Natural History) became an independent museum with its own board of trustees, although – despite a proposed amendment to the act in the House of Lords – the former name was retained. In 1989 the museum publicly re-branded itself as the Natural History Museum and stopped using the title British Museum (Natural History) on its advertising and its books for general readers. Only with the Museums and Galleries Act 1992 did the museum's formal title finally change to the Natural History Museum.
