- Administrative/biographical history:
- Siegmund Warburg was born on the 30 September 1902 in Tubingen, Germany to George Siegmund Warburg and Lucie Kavlla. Warburg attended a humanist school before joining the family firm M. M. Warburg & Co. in Hamburg in 1920 and in 1926 he was sent to London to undertake an apprenticeship with N.M.Rothschild and Sons. He married Eva Marie Philipson in 1926 and they had two children - George born in 1927 and Anna born in 1930. In May 1927 Warburg moved to the United States first working for the company Lybrand, Ross Brothers and Montgomery, then the International Acceptance Bank before working for Kuhn Loeb. He returned to Germany in 1928 and spent a short term in Berlin before moving to New York then London in 1934. In 1935 Warburg founded the financial services company the New Trading Company along with his colleague Henry Grunfeld. This became the merchant bank S. G. Warburg & Company on the 28 January 1946.In 1953 Warburg became an unofficial partner in Kuhn Loeb which he would remain until 1964. In 1954 ninety-nine per cent of shares of S. G. Warburg & Co. were acquired by the holding company Mercury Securities and the bank was floated on the London Stock Exchange. In 1958 S. G. Warburg and Co. became involved in what became known as the 'Aluminium war', the first hostile takeover of a public company in the United Kingdom, when Tube Investments bought British Aluminium under the advice of Warburg. In 1963 the first European Eurobond was issued by the Italian motorway network Autostrade supported by a $15 million loan organised by S. G. Warburg & Co. Warburg had a great interest in politics and founded the Council for Freedom and Justice with the economist Fritz Demuth - an economic committee to discuss ways of undermining the Germany war economy. He also proposed the formation of the bipartisan organisation the Friends of the Atlantic Union, whose members went on to include Hugh Gaitskell, Jo Grimond, Lionel Robbins and Hartley Shawcross. Warburg had many personal interests including graphology - the study of handwriting, Jewish and Israeli affairs and the collecting of aphorisms with view to publishing the compendium "An Anthology for Searchers". He died in London on the 22 October 1982.
