John McKellar Stewart

John McKellar Stewart was born on 4 May 1878 at Ballangeich, near Warrnambool, Victoria, son of Alexander Stewart, a farmer from Scotland, and his native-born wife Lillias, née McKellar. John became a pupil teacher at Warrnambool State School and then taught at Charlton and Benalla. He entered Ormond College at the University of Melbourne in 1903.

In 1906 Stewart topped his final year in philosophy with first-class honours; he won a Hastie scholarship and lectured to Ormond College students in 1907-09, while studying theology and ministering in the Presbyterian Church.

On 3 November 1909 at Scots Church, Melbourne, the serious and friendly young man married Margaret Grace Stuart Bothroyd (M.A.) who later wrote for the Argus and was active in the League of Women Voters; they were to have a daughter and three sons. Stewart proceeded to the University of Edinburgh, where he wrote a thesis on Bergson's philosophy (D.Phil., 1911), and the Philipps University of Marburg, Germany, noted for its Kantian scholarship. His A Critical Exposition of Bergson's Philosophy (London, 1913) portrayed his subject through somewhat Kantian eyes and resisted Bergson's anti-intellectualism.

Having returned to the University of Melbourne in 1912 as lecturer in philosophy, in 1920 Stewart attained the newly established rank of associate professor. As vice-president of the university's controversial Public Questions Society, Stewart showed diplomacy in defending contentious students against an outraged professoriate. He was honorary secretary of the university extension board. 

In 1923-50 he held the Sir Walter Hughes chair of philosophy at the University of Adelaide. He published occasional lectures and journal articles, especially in the Australasian Journal of Psychology and Philosophy; although his manuscript for a book on Husserl was destroyed by a fire in 1939, some of Stewart's translations from Husserl have survived. As a teacher, he prepared lectures meticulously.

He was active outside academic philosophy as vice-chancellor of the university in 1945-48 and as a member of its council; he was also president of the Kindergarten Union of South Australia and a member of the Australian Round Table. In 1949 he was appointed C.M.G.

The professor died in Calvary Hospital, North Adelaide, on 25 April 1953 and was cremated.
