James Maurice Wilson (6 November 1836, Castletown, Isle of Man – 15 April 1931, Steep, Petersfield, Hampshire, England) was a British priest in the Church of England as well as a theologian, teacher and astronomer. Early life Wilson and his twin brother, Edward Pears Wilson, attended King William's College on the Isle of Man from August 1848 to midsummer 1853 (his twin died in December 1856). Their father Edward, vicar of Nocton in Lincolnshire, had earlier been headmaster there. According to his autobiography, Wilson had a rather unhappy time at King William's College. He later studied at Sedbergh School. Wilson entered St John's College, Cambridge, in 1855, where he was Senior Wrangler in 1859. He received a Master of Arts degree in 1862 and was a fellow from 1859 to 1868. Career Wilson was a major figure in the development and reform of Victorian public schools and promoted the teaching of science, which had until then been neglected. He was maths and science master at Rugby School from 1859 to 1879 and headmaster of Clifton College from 1879 to 1890. He made astronomical observations (particularly of double stars) at Temple Observatory at Rugby with his former student George Mitchell Seabroke. Temple Observatory was named after Frederick Temple, headmaster of Rugby School, who later became Bishop of Exeter and Archbishop of Canterbury. Wilson was encouraged by Temple to write the textbook Elementary Geometry, which was published in 1868. Until that time, Euclid's Elements had remained the standard textbook used in British schools. With Joseph Gledhill and Edward Crossley, Wilson co-wrote Handbook of Double Stars in 1879, which became a standard reference work in astronomy. His astronomical observations seem to have come to an end after he left Rugby and went to Clifton. While at Clifton, he successfully pushed for the creation of St Agnes Park in Bristol, as part of a plan to improve the lives of the urban poor. After his teaching career, he became Vicar of Rochdale, Archdeacon of Manchester from 1890 to 1905, a canon of Worcester Cathedral from 1905 to 1926 and vice-dean of the cathedral. He was Hulsean lecturer at Cambridge in 1898; Lady Margaret Preacher at Cambridge in 1900; and Lecturer in Pastoral Theology at Cambridge in 1902. He wholeheartedly accepted the theory of evolution and its implications for the literal interpretation of the Bible. He gave two lectures in 1892 in which he accepted
