John Arthur Porter (November 12, 1921 – June 15, 1979) was a Canadian sociologist from 1950 to the late 1970s. His work in the field of social stratification opened up new areas of inquiry for many sociologists in Canada. Porter was born in Vancouver and completed his education at the London School of Economics in the United Kingdom. There, he became interested in studies of social class. On returning to Canada he joined the faculty of Carleton University. He remained at Carleton as a professor, and later, as department chairman, dean and academic vice-president. He was also visiting professor at Harvard and the University of Toronto. Early life At 15 John Porter's father lost his job in Vancouver and his family moved to England in search of stable work. Luck, however, was not found.

John who had left high school in Vancouver was never able to return as he searched and worked for subsistence. Known for being a gifted student who had a particular proficiency in creative writing, he continued his studies informally with his mother—a schoolteacher. War broke out and in 1941 Porter joined the Canadian Army as an Intelligence Officer and, towards the end of the war in 1943, he was part of the Allied invasion of Italy and Sicily. After the war he worked with a colonel in London writing a history of Canada's involvement in the war while studying for the entrance exam to the London School of Economics—which he passed on his first attempt. He joined the school at a particularly important ferment: while the university had abandoned its social democratic and Fabian roots, its professors and students were heavily influenced by a liberal reformism which, in the words of one commentator, was "a widely shared belief that the irrationality of war and suffering could be eliminated by the judicious application of humane rationality specifically manifested in the form of a generous and intelligent welfare state." Reflecting upon his time as the LSE Porter notes that he was most animated by "a concern for ethical principles in social life." In 1949 he graduated and, after a twelve-year hiatus, returned to Canada. He was offered a job teaching political science at the adolescent Carleton College and, two years
