Robert W. Haack

In 1976, after several international bribery scandals which involved the Lockheed Aircraft Corporation and other American companies, Haack was named chairman of the Lockheed Aircraft Corporation. During his twenty months as chairman, he worked to "restore confidence in the company and revised its finances based around a Federal loan guarantee." He retired in September 1977.

On April 1, 1964, he became president of the National Association of Securities Dealers (predecessor to the Financial Industry Regulatory Authority). He left the NASD in 1967 to become the fourth full-time president of the New York Stock Exchange, the nation's largest stock exchange. While president of the Exchange, "he put a high priority on development of several automation programs, including one intended to reduce the physical movement of securities from one brokerage house to another." During the near collapse of the financial markets in 1970, dozens of brokerage firms either collapsed or were forced into mergers, including prominent firms like Hayden Stone, Inc. and F. I. du Pont. Haack responded by working with Congress to develop the Securities Investor Protection Corporation. Prior to the end of his term, Haack was an early and strong advocate for ending fixed commission rates at the NYSE and moving to the negotiated rates we have today. After his term as president ended in 1972, there was no president of the Exchange between May 1972 until May 1980 when John J. Phelan, Jr. assumed the presidency.

In 1942, Haack married Catharine Rademaker, the daughter of Walter Rademaker and the granddaughter of Godfrey Augustyn, a past president of the Marine National Bank in Milwaukee. After the passing of Catharine in 1984, Haack married Ann (Née Thornett) Miller in 1990 (1930–2004), the daughter of Geoffrey Matthew Thornett former wife of Allison N. Miller Jr. He was the father of four children, one son, Thomas Haack, and three daughters, Barbara Haack Sexton, Elizabeth Haack Barr, and Linda Haack Brooks.

In 1940, he returned to Milwaukee where he began his career in the securities industry as a stockbroker with Robert W. Baird & Company. After moving from trader to head of the department, then syndicate manager and later institutional sales manager, he became a partner at Baird in 1950 before moving to Washington in 1964.

In 1938, he graduated from Hope College, the private, Christian liberal arts college in Holland, Michigan. After Hope, he attended Harvard Business School on a scholarship provided by Milwaukee alumni, where he graduated in 1940.
