Arthur Levitt Jr. was the twenty-fifth and longest serving Chairman of the United States Securities and Exchange Commission (SEC) from 1993 to 2001.
After sixteen years on Wall Street, Levitt became the Chairman of the American Stock Exchange (AMEX) in 1978. In 1989, he left the AMEX to serve as Chairman of the New York City Economic Development Corporation until 1993. Before joining the SEC, Levitt owned ?Roll Call?, a newspaper that covers Capitol Hill.
During Levitt’s tenure at the SEC, he was widely viewed as a pro-investor advocate and received favorable press coverage. However, more recently he has come under criticism for failing to act against 1990s bull market abuses.
In 2005, Levitt was named a special advisor to the American International Group’s board of directors and the board’s nominating and corporate governance committee following the resignation of CEO and Chairman Maurice “Hank” Greenberg..
