For some years Stern was heir-apparent to his father-in-law, Michel David-Weill, chairman and controlling shareholder of the investment bank Lazard Freres. A great-grandson of one of the firm's founders, David-Weill had run the tripartite group - which has operations in Paris, London and New York - since 1977; and in 1992 he brought in Stern to be a senior partner in Paris and New York.
Stern also became a significant shareholder in Lazard's holding companies, and a power struggle swiftly ensued between the two men. It was reported that Stern's aggressive manner led to his being ejected from two of the bank's senior committees. He departed angrily in 1997 to run his own investment fund, leaving a vacuum that was filled by the arrival of the Wall Street veteran Bruce Wasserstein as David-Weill's eventual successor.
Although Stern had close links with two of Lazard's biggest French customers (the Elf oil company and the cosmetics group L'Oréal), David-Weill said that smooth handling of clients was not Stern's strong suit: "He is much more talented as a businessman than in service activities." The French press labelled Stern le gendre incontrôlable (the uncontrollable son-in-law).
The circumstances of his death remain unexplained: Stern led a private and somewhat mysterious life in Geneva, and was said to have told friends recently that he felt threatened. Theories in financial circles include the possible involvement of the Russian mafia.
Edouard Stern was born on October 18 1954, the son of a Jewish father and a French mother. He graduated from the Ecole Superieure de Science Economiques et Commerciales in Paris, and joined his family's private investment house, Banque Stern, in 1977.
