William Arthur was a Wesleyan Methodist minister and author. Born at Newport, in the county Mayo, eight miles from Castlebar, Arthur was educated at Horton College, and at the age of twenty was sent to Goobbee, in Southern India, where he was engaged for several years in missionary work in the Mysore. While there his progress in the Canarese language is said to have been remarkable; but being threatened with blindness, he was obliged to return to Europe, and was employed for three years in advocating with much ability the Indian missionary work of the Wesleyan Society. He acted in his ministerial capacity in Paris from 1846 to 1849; then for seventeen years he filled the post of secretary to the Methodist Missionary Society. In 1867 he was elected Principal of the Methodist College Belfast, and continued to fill that office until 1871, when he resigned, but still maintained his connection with the Conference as honorary missionary secretary. In 1866-67 he was President of the Wesleyan Conference.
