Maurice Raymond "Hank" Greenberg (born May 4, 1925 in New York City) is a businessman and former chairman and CEO of American International Group (AIG), which under his tenure, was the world's 18th largest public company and its largest insurance and financial services corporation.
He is currently chairman and CEO of C.V. Starr and Company, a diversified financial services firm that is named for the founder of AIG, Cornelius Vander Starr.
Greenberg is married and has four children. He is the father of Jeffrey W. Greenberg, former chairman and CEO of Marsh & McLennan Companies (MMC) before he was ousted, and of Evan G. Greenberg, president and CEO of ACE Limited. Together, he and his sons controlled a major portion of the insurance industry.
In 1962, Greenberg was named by AIG's founder, Cornelius Vander Starr, as the head of AIG's failing North American holdings. In 1968, Starr picked Greenberg as his successor. Greenberg held the position until 2005, when he stepped down amid a major accounting scandal and was replaced by Martin J. Sullivan.
Greenberg was both a social friend and client of Henry Kissinger, utilising his consultancy, Kissinger Associates, for advice and operations in a number of countries, particularly in Asia. In 1987 he appointed Kissinger as chairman of AIG's International Advisory Board.
On March 15, 2005, AIG's board forced Greenberg to resign from his post as Chairman and CEO under the shadow of criticism from Eliot Spitzer, attorney general of the state of New York. On May 26, 2005, as part of a series of actions against leaders of large corporations, Spitzer filed a complaint against Greenberg, AIG, and Howard I. Smith (ex-CFO of AIG) alleging fraudulent business practice, securities fraud, common law fraud, and other violations of insurance and securities laws. Greenberg's public statements show that he found the Spitzer investigation to be very troubling. He maintained his innocence throughout the investigation, and alluded to the possibility that Eliot Spitzer might be conducting a high-profile witch-hunt in the interests of furthering his political ambitions.
After a subsequent investigation, however, all criminal charges were dropped, and Greenberg was not held responsible for any crimes. The New York State Attorney General's office however is still pursuing Mr. Greenberg in civil court for many of these same criminal allegations.
