<P> Keynes was ultimately a successful investor, building up a private fortune . His assets were nearly wiped out following the Wall Street Crash of 1929, which he did not foresee, but he soon recouped . At Keynes's death, in 1946, his net worth stood just short of £ 500,000--equivalent to about £ 11 million ($16.5 million) in 2009 . The sum had been amassed despite lavish support for various good causes and his personal ethic which made him reluctant to sell on a falling market, in cases where he saw such behaviour as likely to deepen a slump . </P> <P> Keynes built up a substantial collection of fine art, including works by Paul Cézanne, Edgar Degas, Amedeo Modigliani, Georges Braque, Pablo Picasso, and Georges Seurat (some of which can now be seen at the Fitzwilliam Museum). He enjoyed collecting books; he collected and protected many of Isaac Newton's papers . In part on the basis of these papers, Keynes wrote of Newton as "the last of the magicians ." </P> <P> Keynes successfully managed the endowment of King's College, Cambridge, with the active component of his portfolio outperforming a British equity index by an average of 8% a year over a quarter century, earning him favourable mention by later investors such as Warren Buffett and George Soros . </P> <P> Keynes was a lifelong member of the Liberal Party, which until the 1920s had been one of the two main political parties in the United Kingdom, and as late as 1916 had often been the dominant power in government . Keynes had helped campaign for the Liberals at elections from about 1906, yet he always refused to run for office himself, despite being asked to do so on three separate occasions in 1920 . From 1926, when Lloyd George became leader of the Liberals, Keynes took a major role in defining the party's economic policy, but by then the Liberals had been displaced into third party status by the Labour Party . </P>
