The Senate committee hearings that Pecora led probed the causes of the Wall Street Crash of 1929 that launched a major reform of the American financial system. Pecora, aided by John T. Flynn, a journalist, and Max Lowenthal, a lawyer, personally undertook many of the interrogations during the hearings, including such Wall Street personalities as Richard Whitney, president of the New York Stock Exchange, George Whitney (a partner in J.P. Morgan & Co.) and investment bankers Thomas W. Lamont, Otto H. Kahn, Albert H. Wiggin of Chase National Bank, and Charles E. Mitchell of National City Bank (now Citibank). Because of Pecora's work, the hearings soon acquired the popular name the Pecora Commission, and "Time" magazine featured Pecora on the cover of its June 12, 1933, issue.
