David Bensusan-Butt

David Miles Bensusan-Butt (24 July 1914, Colchester—25 March 1994, London) was an English economist who spent much of his career in Australia. Known as David, he published his work as D. M. Bensusan-Butt.

A nephew of the French Impressionist painter Camille Pissarro, and the son of Dr Ruth Bensusan-Butt (1877–1957), the first woman doctor to work in Essex, Bensusan-Butt was educated at Gresham's School, Holt, and King's College, Cambridge, where he was a student of John Maynard Keynes and indexed Keynes's magnum opus, the General Theory of Employment, Interest and Money. Bensusan-Butt acted as an assistant to Keynes, for searching literature and writing references, making him Keynes's best-informed student on progress with the project, so that one historian of economics has described him as 'the favoured man'.

After a short period working for The Economist, Bensusan-Butt joined the civil service in 1938. Early in the Second World War he became private secretary to Frederick Lindemann, 1st Viscount Cherwell, then worked for Winston Churchill. While he was First Lord of the Admiralty, Churchill created a Statistical Section in the Admiralty which was joined by Bensusan-Butt, Roy Harrod, Bryan Hopkin, Douglas MacDougall and Tom Wilson.
