Osborne Reynolds's father, a clergyman and schoolteacher, had been a Fellow of Queens' College, Cambridge; it was to Queens' that the young Reynolds went to study mathematics, graduating as 7th Wrangler in 1867, and going on in his turn to become a Fellow of the College. Reynolds had developed an interest in practical applications of physics and engineering, and for a short time he entered the office of the London civil engineers Lawson and Mansergh. In 1868 he was appointed to the new Chair of Engineering at Owens College, Manchester, and he remained in this post for thirty-seven years, until he retired in 1905. During this period he presided over a department that grew steadily in size and reputation, and undertook prolonged research projects into phenomena such as lubrication, the laws governing the flow of water in pipes, turbulence and other physical features with practical applications. He was elected a Fellow of the Royal Society in 1877, being nominated Royal Medallist in 1888. In 1883 he became a Member of the Institution of Civil Engineers, and in 1885 he was awarded the Telford Premium of the Institution. He served as Secretary of the Manchester Literary and Philosophical Society from 1874 to 1883, and was appointed President in 1888–9 and Dalton Medallist in 1903. He was President of Section G of the British Association for the History of Science in 1887, and in 1884 he received the degree of LLD from Glasgow University. Among his many students at Owens College was J.J. (later Sir Joseph) Thomson (1856–1940), who entered the college in 1871. Reynolds's collected scientific papers were published in 1900–3.
