John Raymond Wilton
John Raymond Wilton was born on 2 May 1884 at Belfast (Port Fairy), Victoria, son of Charles Richard Wilton, architect, and his wife Annie Isabel, née Gladstones, both native-born. His early years were spent at Mount Barker, South Australia, where his father (later chief of the Adelaide Advertiser's literary staff) was editor of the Mount Barker Courier.
Educated at Prince Alfred College in 1891-1901, Raymond won the old collegians' scholarship and an Angas engineering exhibition. At the University of Adelaide (B.Sc., 1903) he graduated with first-class honours in mathematics and in physics.
Professor William Henry Bragg described Wilton as having had the greatest natural genius for mathematics among any of his students; on his advice, in 1904 Wilton proceeded to Trinity College, Cambridge (B.A., 1907; M.A., 1911). Awarded a sizarship in 1905, he also won the Jeston scholarship; in the mathematical tripos examination of 1907 he was fifth wrangler; next year he took the second part of the natural science tripos and gained first-class honours in physics.
After a period of research in the Cavendish Laboratory, Cambridge, in 1909 Wilton was appointed assistant lecturer in mathematics at the University of Sheffield. On 5 September 1910 at St John's Church, St Teath, Cornwall, he married Annie Martha Gladstone (d.1932).
The University of Adelaide awarded Wilton its first D.Sc. in mathematics in 1914; by 1916 he had published a prodigious twenty-five research papers on partial differential equations, hydrodynamics and elliptic functions.
During World War I he suffered as a pacifist. Before the introduction of conscription, Wilton had undertaken X-ray work in a Sheffield hospital, but in 1916 was directed to London where repetitive tasks and financial privation contributed to his breakdown in June 1918. After the war he joined the Society of Friends and taught briefly at one of their schools. Having accepted an assistant lectureship in mathematics at Owens College, Victoria University of Manchester, under Horace Lamb, in 1919 Wilton was appointed Thomas Elder professor of mathematics at the University of Adelaide.
Back in Adelaide in 1920, he found the mathematical courses much the same as those he had attended as an undergraduate. Although he revised the curricula, as well as those at the senior school level, he was not successful in encouraging honours students, only eight of whom graduated between 1920 and 1940. In 1926-34 Wilton published twenty-six research papers on analysis and number theory: his sustained research gained him a doctorate in science from the University of Cambridge in 1930 and the Lyle medal in 1935 from the Australian National Research Council.
Beyond mathematics, Wilton's prime interests were music and literature. He read Dante's Divine Comedy in Italian several times a year for twenty years. The Faculty of Arts at the University of Adelaide acknowledged him as 'a scholar of powerful and sensitive intellect who united highly specialised learning with a broad and deep culture, and a gentleman of unassuming demeanour, warm sympathy, just judgment and steadfast devotion to principle'.
A stroke in 1941 so impaired Wilton's speech and memory that 'he had to learn mathematics afresh, even his multiplication tables'. In 1944 he returned to lecturing, but died of a cerebral haemorrhage on 12 April at the Wakefield Street private hospital, Adelaide, and was buried in West Terrace cemetery.
His wife Winifred Aimée, née Welbourn, whom he had married on 25 May 1936 at the Friends Meeting House, North Adelaide, survived him, as did their daughter.Biographical SourceTaken from Australian Dictionary of Biography, Volume 12, (MUP), 1990
