George Cockburn Henderson

George Cockburn Henderson (1870-1944), historian, was born on 1 May 1870 near Newcastle, New South Wales, eighth of nine children of Richard Henderson, an English coalminer who was a Methodist and illiterate, and his wife Ann, née Robinson. Henderson was educated at Hamilton Public School and Fort Street Model School, Sydney. He became a pupil-teacher and in 1889 went to the Fort Street Training School and next year to the University of Sydney (B.A., 1893). In his final year he won the University medal, (Sir) Francis Anderson's prize and the Frazer scholarship; he was markedly influenced by Professors Anderson, George Wood and (Sir) Mungo MacCallum. He resumed schoolteaching and joined the university's extension lecture staff. Next year the university awarded him the James King of Irrawang travelling scholarship; he studied history and philosophy at Balliol College, Oxford (B.A., 1898; M.A., 1901). Henderson enjoyed Oxford life and worked with an East London settlement conducted by Mansfield College. His final second-class honours were unexpectedly disappointing.

On 5 January 1899 at Leicester, Henderson married May Gertrude Sturge, a Quaker writer, and went with her to Sydney as acting professor of history and, next year, of philosophy. In September they returned to England and he resumed extension work. In 1901 in Italy he examined intensively the life of St Francis of Assisi. Next year the University of Adelaide appointed Henderson to the chair of modern history and English language and he began lectures in June. His wife stayed behind; in 1911 they were divorced. Henderson's domestic life blended boarding-houses with the Adelaide Club and he had many friends. However, he experienced periods of acute mental depression.

Henderson's innovative 1907 syllabus included Imperial and colonial history; that year he published Sir George Grey, Pioneer of Empire in Southern Lands. Its research had shown him the need for collections of local historical records, so he arranged through Thomas Gill the purchase by the local branch of the Royal Geographical Society of Australasia of S. W. Silver's valuable York Gate library. In 1909 he lectured on early South Australian history and also persuaded (Sir) George Murray to establish the Tinline scholarship to commemorate his mother's family name, the holders to examine the State's history from original records.

Henderson believed that Australian universities should foster interest in Australian history, and undertake a 'systematic and scientific' history of the British Empire. In 1914 he spent a year's leave overseas and as a member of the Public Library, Museum and Art Gallery board, reported on European archives and record offices; the outcome was the opening in 1920 of the South Australian archives department, the first in Australia.

In 1922 Henderson's enormous teaching load was relieved by the appointment of extra staff, but his health remained precarious. Despair filled him every morning and he endured severe insomnia. On 27 October he married in Adelaide Dr Annie Heloise Abel, an American historian, but his mental state worsened. In June 1923 he was hospitalized; his wife returned home and the marriage was later dissolved. Henderson resigned and was made emeritus professor in 1924.

Though he was tended lovingly by nieces and nephews on his small property at Dora Creek near Lake Macquarie, Henderson's last years were depressed. He struggled against this, but he felt that 'his brain was on fire'. He committed suicide in his garden on 9 April 1944 and was buried in Sandgate Methodist cemetery. There were no children and the residue of his estate of £14,919 went to the University of Sydney to found the G. C. Henderson research scholarship for work on the South Pacific islands. He is commemorated in the history department of the University of Adelaide by the Henderson room (which includes part of his library) and the Henderson Jubilee Fund—History.
