Maurice R. Greenberg

In July 2022, Greenberg announced the founding of a group composed of senior U.S. business and policy leaders who share the view that the United States should engage more constructively with China. Greenberg stated, "The deteriorating state of affairs between the U.S. has destabilized the most important bilateral relationship in the world," and the new group is intended to "help foster a meaningful but frank exchange between the U.S. and Chinese governments on issues of mutual concern."

In 1962 Greenberg was named by AIG's founder, Cornelius Vander Starr, as the head of AIG's North American holdings after working for Continental Casualty Company, a unit of CNA in Chicago. In 1968 Starr picked Greenberg as his successor. Greenberg held the position until March 2005, when he retired from AIG and was replaced by Martin J. Sullivan. He was subsequently the subject of New York State civil charges which were resolved on February 10, 2017, subject to a settlement (without any admission of wrongdoing) with the office of the New York Attorney General. Greenberg is a social friend and was a client of Henry Kissinger. In 1987 he appointed Kissinger as chairman of AIG's International Advisory Board.

The State Attorney General's Office pursued Greenberg in a New York State civil court action which concluded with a settlement (without any admission of wrongdoing) on February 10, 2017. Eliot Spitzer did bring civil charges against Greenberg, though Spitzer and his successors dropped seven of the nine initial charges. Those charges were brought under a 1921 New York State blue sky law (the Martin Act) that authorizes the New York Attorney General to seek relief for alleged violations of the state securities laws without the need to prove a knowing violation of the law (scienter) or an intent to defraud.

As chairman of The Starr Foundation, Greenberg oversees the disbursement of major financial support to academic, medical, cultural, and public policy institutions. He is also the former chairman of The National Interest. The Maurice "Hank" Greenberg Scholarship, administered in his name by the US-China Education Trust, supports the studies of ten Chinese students from low-income families each year at Yunnan University. In February 2014 Greenberg led a group through Starr Investment Holdings that acquired health insurance claims processor MultiPlan Inc for around $4.4 billion. This group, on May 5, 2016, sold MultiPlan Inc. to Hellman & Friedman for approximately $7.5 billion.

In July 2013 Greenberg filed a civil lawsuit against Spitzer alleging that Spitzer made repeated defamatory statements against him. This matter was stayed pending a decision on cross-appeals that were argued before the Second Department of New York's Appellate Division in March 2016. In December, 2013 Greenberg filed a complaint with the New York State Joint Commission on Public Ethics alleging that New York State Attorney General Eric Schneiderman had violated the state's public officer's law by making disparaging comments about him that could potentially taint a jury venire in any trial. On September 13, 2016, the accounting fraud case against Greenberg came to trial in a state courthouse in Lower Manhattan 11 years after he was first charged. The case ultimately settled with Greenberg agreeing to pay $9.9 million.

Greenberg is a major Republican donor. He donated to Mitt Romney's presidential candidacy. In the Republican Party presidential primaries, 2016 he donated $10 million to support Jeb Bush's candidacy and at a later point also donated $5 million to Conservative Solutions PAC which supported Marco Rubio's campaign.

Greenberg and Lawrence Cunningham wrote The AIG Story, published in 2013.

In November 2012 a Manhattan court dismissed Greenberg's claims that the Federal Reserve Bank of New York breached its fiduciary duties to AIG shareholders. In late 2011 Greenberg's Starr International announced a lawsuit against the federal government. According to Reuters, the lawsuit seeks $55.5 billion in damages against the government stemming from the government's financial bailout in 2008. Following a lengthy trial in Fall 2014, the Court of Federal Claims ruled in June 2015 that the federal government acted without authority, but did not award any damages. In a decision on appeal in the US Court of Appeals for the Federal Circuit in Washington, DC, a three judge panel remained silent with regard to the Court of Claims decision on both liability and damages, but claimed that Starr lacked standing to file the suit in question, holding that standing belonged solely to AIG. The Supreme Court declined in 2018 to review the case. The market value of the 79.9% of AIG common stock the government acquired on the day of the government agreed to loan AIG up to $85 billion was $55.4 billion. By the end of 2012, AIG had repaid all of its loans and the government had made a $17.7 billion profit on the AIG equity it had acquired as a result, plus $6.7 billion in interests and fees.

In 2008 he appeared on ABC's "Good Morning America" criticizing the board of directors of AIG. In an interview with Reactions magazine in March 2010, serialized over three parts, Greenberg stated that he did not condone AIG's strategy of selling non-core assets to pay back the United States government, and believed the terms under which AIG was provided access to bail-out funds needed to be renegotiated.

Greenberg gained visibility when he clashed with Mahmoud Ahmadinejad over the Iranian president's denial of the Holocaust. On September 20, 2006, the Council on Foreign Relations hosted a small meeting of select council members with Ahmadinejad, who began by saying that we need to "continue studying" whether it happened. According to David E. Sanger, Chief Washington Correspondent for The New York Times, Greenberg listened for fifteen minutes while Ahmadinejad continued talking about the Palestinians, World War II, and if the Holocaust killings had happened at all. Sanger writes, "Then Hank Greenberg, who had been on a slow boil through the evening, spoke up. He had been a young soldier at the end of the war, and participated in the liberation of the camps. 'I went through Dachau in the war and saw with my own eyes.'" President Ahmadinejad responded by asking if Greenberg was old enough to have participated in the liberation of Dachau. "I'd like an answer regarding whether you think the Holocaust occurred," insisted Greenberg. To which Ahmadinejad replied "I think we should allow more impartial studies to be done on this."

Greenberg's career is chronicled in the 2006 book Fallen Giant: The Amazing Story of Hank Greenberg and the History of AIG. He and his son, Jeffrey, are also discussed in the 2011 book All the Devils Are Here: The Hidden History of the Financial Crisis. Greenberg is discussed in the 2011 book, Wealth Management: Private Banking, Investment Decisions, and Structured Financial Products He is noted in the 2012 book, Black 9/11: Money, Motive and Technology

In 2003, Vladimir Putin pursued an economic agenda for Russia to begin normalized trade relations with the West which included the repeal of the Jackson–Vanik amendment. Putin tried to use his relationship with Hank Greenberg to repeal the Jackson-Vannik provisions in the United States. Putin wanted Greenberg to support through American Insurance Group greater development of the nascent Russian home-mortgage market.
