Nicknamed "L'Avvocato" ("The Lawyer") because he had a degree in law (though he was never admitted to the Order of Lawyers), Agnelli was the most important figure in Italian economy, the symbol of capitalism throughout the second half of 20th century, and regarded by many as the true "King of Italy". A cultivated man of keen intelligence and a peculiar sense of humour, he was perhaps the most famous Italian abroad, forming deep relationships with international bankers and politicians, largely through the Bilderberg Group, whose conferences he attended regularly since 1958. Some of the other Bilderberg regulars became close friends, among them Henry Kissinger. Another longtime associate was David Rockefeller (yet another Bilderberg regular), who appointed him to the "International Advisory Committee" (IAC) of Chase Manhattan Bank, of which Rockefeller was chairman; Agnelli sat on this committee for thirty years. He was also a member of a syndicate with Rockefeller that for a time in the 1980s owned Rockefeller Center.
