Dr Joseph Houldsworth Oldham (1874 - 16 May 1969) was educated at Edinburgh Acadamy and Trinity College, Oxford. He was involved in the Christian movement from early in his career, being the secretary of the Student Christian Movement and subsequently the secretary of the Y.M.C.A. at Lahore, Pakistan. In 1908 he was appointed secretary for the World Missionary Conference held in Edinburgh two years later. He worked to promote Ecumenicalism, unity and the extension of Christendom. His activity in Africa from 1919 influenced educational policy through missionary societies. In many ways he was the driving force behind the Moot. He was the honorary chairman of the World Council of Churches from 1961 until his death.
