1859-1936. Canadian Presbyterian missionary to China. Educated at Knox College, Toronto, he was ordained in 1886 and with his wife went to China (1887) where they were pioneers in the Canadian Presbyterian work in Honan Province. Theologically conservative and a firm believer in preaching, he became famous for his leadership and participation in the revivals which swept over China in the early twentieth century. Though he lost his eyesight during his final years in China, he continued to minister there until 1934. He wrote By My Spirit, which told of the remarkable revivals in China and which inspired much support for missions.
