REGAN, DONALD T.
Joining Merrill Lynch, Pierce, Fenner and Smith as a trainee in 1946, Regan progressed through the ranks until 1968, when he was elected president. He was elected chairman and chief executive officer in 1971, and assumed these positions in the holding company, Merrill Lynch & Co., when it was formed in 1973. He served as U. S. Treasury Secretary under Ronald Reagan, 1981-1985, after which point he became Reagan's chief of staff, serving in that position until 1987. In this latter capacity, Regan directed the day-to-day operations of the White House and the President's staff, served as the President's senior advisor, and had supervisory responsibility for the Executive Offices. Considered by many to be an abrasive and arrogant individual, he resigned under fire after an all-too-public spat with First Lady Nancy Reagan over his private criticisms of President Reagan.
