Keynes died of a heart attack at his holiday home in Tilton, East Sussex. His heart problems were made worse by the strain of working on post-war international financial problems. He died soon after he arranged a guarantee of an Anglo-American loan to Great Britain. Keynes' father, John Neville Keynes (1852–1949) outlived his son by three years. Keynes's brother Sir Geoffrey Keynes (1887–1982) was a distinguished surgeon, scholar and bibliophile. His nephews include Richard Keynes (born 1919) a physiologist; and Quentin Keynes (1921–2003) an adventurer and bibliophile. Keynes did not have children.
