Darman was chief architect of a compromise designed to reduce the federal budget deficit. Although it drew praise from many economic analysts, the plan included tax increases that broke Bush 1988 election promise, "Read my lips, no new taxes!" The change of policy contributed to Bush's re-election defeat to Bill Clinton in 1992.
A talented and tough negotiator, Darman sometimes drew criticism for being abrasive, intellectually arrogant and overly concerned with his standing in the White House pecking order. He had a reputation for being so crafty that "Darmanesque" became a word to describe maneuvering that was clever and Machiavellian.
Darman had a more playful side and was known for pranks. He once donned a gorilla suit to amuse his boss, the president.
Darman's hardball tactics on Capitol Hill in budget negotiations alienated many senior Republicans in Congress and many White House colleagues. He railed against budget gimmicks and called for serious steps to get the budget under control.
The government's huge budget deficits were "a mathematical representation of our wish to buy now, pay later -- or more accurately, buy now and let others pay later," he said. He criticized the nation's obsession with its current finances and "our reluctance to adequately address the future."
But those words were from the same man who earlier had served as a top political strategist for President Ronald Reagan and helped craft an economic policy that stressed tax cuts even as federal budget deficits were reaching record levels.
"Dick Darman was a brilliant, dedicated, and distinguished public servant, educator, and businessman who could direct traffic through the intersection of policy and politics as well as anybody I have ever known," said Baker, who worked with Darman under presidents Bush and Reagan.
Darman began his government career in 1971 as a deputy assistant secretary in the former Department of Health, Education and Welfare. He later held high-level posts in the Defense, Justice and Commerce departments. He served as a top aide to Attorney General Elliot Richardson, who lost his job in the "Saturday Night Massacre" during the Watergate scandal.
Darman was deputy chief of staff to Reagan while Baker was running the staff. Baker became his mentor, which helped Darman survive in the Bush White House. When Baker switched jobs to become Treasury secretary, Darman went with him, becoming deputy Treasury secretary.
"He was absolutely brilliant at boiling down complex issues to their simplest forms," Baker said. "He always provided me with an unvarnished perspective that I needed to know, even if sometimes I didn't want to hear it.
Along with his jobs in many federal agencies, Darman taught at Harvard University's John F. Kennedy School of Government and the Harvard Business School.
The son of an industrialist, Darman was born in Charlotte, N.C. and raised in Rhode Island and Massachusetts. He received an undergraduate degree from Harvard in 1964 and an M.B.A. from the Harvard School of Business.
Darman is survived by his wife Kathleen and three sons, William, Jonathan, and Emmet.
