Darwin, fourth and last surviving son of Charles Darwin and Emma Wedgwood, was born at Down House near Downe, Kent on 15 January 1850 and died in London on 26 March 1943. He entered the Royal Military Academy at Woolwich in 1868, and came second on the examination list, to his father's great joy. He served in the Royal Engineers, rising to the rank of major by 1890, and on scientific expeditions to photograph the transit of Venus. He taught at the School of Military Engineering at Chatham from 1877–82, and served in the intelligence division of the Ministry of War from 1895–90. He entered parliament in 1892 as Liberal-Unionist MP for Lichfield, holding the seat until 1895, during which time he began a serious study of economics. From 1908–11 he was president of the Royal Geographical Society.
