Alan C. "Ace" Greenberg (born September 3, 1927) is a
former Chairman of the Executive Committee of The Bear Stearns Companies
Inc.
He began work at Bear Stearns in 1949 as a clerk. He served as Chairman of the Board of Bear Stearns from 1985 to 2001, and as its CEO from 1978 to 1993. Greenberg serves also as a director of Bear Stearns and a non-executive director of Viacom. He is the author of Memos from the Chairman, which is a compilation of humorous but meaningful memos he issued to the associates of Bear Stearns during his tenure as CEO.
While serving as Chairman of the Executive Committee for Bear Sterns, Greenberg saw the collapse of the company in March of 2008. He was subsequently involved in the talks with JPMorgan Chase, who bought out the failing Bear Sterns at $2 a share on March 24, 2008.
On April 24, 2008, it was reported in Fortune that Greenberg agreed to join JPMorgan Chase & Co. as vice chairman of Bear’s retail business.
Greenberg is an avid bridge player, having won the Reisinger Board-a-Match Teams in 1977.
In 1981, he won the Maccabiah Games teams bridge tournament, part of the quadrennial Jewish Olympics, and was second in the Reisinger later that year.
Greenberg is also a member of the Society of American Magicians. In 1998, Greenberg was the subject of a 999-word profile in People Magazine that trumpeted his $1 million donation to New York City's Hospital for Special Surgery to underwrite Viagra prescriptions for financially needy, impotent men.
"You do some nutty things," Greenberg stated and he told People that his wife Kathryn told him, "you've made your money, and you can spend it any way you want." That philanthropic gesture topped the time Greenberg paid to repair the bathrooms at the Israel Museum in Jerusalem.
Alan Greenberg is married to Kathy Greenberg, who is the Board Chair of Cardozo School of Law and the founder of the New York Legal Assistance Group.
