Jeffrey Wayne Greenberg (born 1951) is an American lawyer and business executive, who was chairman and CEO of Marsh & McLennan Companies from 1999 to 2004.
He began his career at Marsh & McLennan after graduation. During the September 11 attacks, 295 staff members were killed. Greenberg was then in midtown Manhattan, at the company's headquarters, with "an unobstructed view of lower Manhattan" where he witnessed "smoke rising from One World Trade Center and the fireball erupt from the second tower." He then led the company's immediate response to the crisis.[2]
Greenberg resigned as CEO of Marsh & McLennan after the firm was charged with conducting a lucrative kickback scheme by then New York State Attorney GeneralEliot Spitzer,[3] who demanded management changes, stating that "The leadership of that company is not a leadership I will talk to and not a leadership I will negotiate with."[4] In 2012, the Financial Times reported that "Mr. Greenberg was never charged with any wrongdoing, while Mr. Spitzer was later engulfed in a prostitute scandal."[5]
Greenberg had a 14-year relationship with journalist Nikki Finke, getting engaged in 1974 and married in 1980. The couple divorced in 1982.[9] He later remarried and has four children.[10]
