Sir Siegmund George Warburg (30 September 1902 – 22 October 1982) was a German-born English banker. He was a member of the prominent Warburg family. He played a prominent role in the development of merchant banking.
Georges Siegmund Warburg and Lucie raised a young Siegmund Warburg on an estate (Uhenfels Castle) in Swabia in South West Germany far away from the main branch of the family, which operated the second largest bank in Hamburg, up north. Siegmund had a sincere and deep affection for his mother who taught him to have a critical and inquisitive mind.
In the period immediately before the Second World War he worked under cover for the Z Organisation, a highly secret offshoot of MI6/SIS, and reported impressively from Switzerland on his regular meetings with Hjalmar Schacht, then the president of the Nazi German Reichsbank and thus the most powerful German banker.
In the United Kingdom, Siegmund was considered an 'upstart' to the establishment in the City of London. His most famous achievement was the establishment of the EuroBond market. He firmly believed that financial integration of Europe was an essential and natural step in the development of the European economy.
The firm that he created with Grunfeld, S.G. Warburg & Co., was a major British investment bank (merchant bank at the time), and Siegmund was the bank's managing director until the 1970s - when although he officially had retired and was living in Switzerland, still retained a personal secretary to draft correspondence and assist with the operations of the firm. Control of the firm S.G. Warburg and Co. was retained through a family controlled holding company called 'Mercury Securities', where stock was allocated to S.G. Warburg & Co. partners as well as his Swedish wife and children.
Warburg was knighted in 1966.
The firm S.G. Warburg & Co. was acquired by UBS AG creating UBS Warburg, which then after a rebranding exercise was dropped, leaving only UBS AG.
He died in London in 1982.
