Duff Hall was erected in the centre of the educational buildings of Calcutta. In 1864, Duff visited South Africa, and on his return, became convener of the foreign missions committee of the Free Church. In 1870 he was the principal force in founding the Anglo-Indian Christian Union (an alliance of Protestant churches to minister to scattered British communities in India), of which he became the first President, and sent Rev.
