H R Haldeman

Harry Robbins "Bob" Haldeman (October 27, 1926 – November 12, 1993) was an American political aide and businessman, best known for his service as White House Chief of Staff to President Richard Nixon and his consequent involvement in the Watergate scandal. Began as an advance man on Pres Dwight D. Eisenhower's reelection campaign in 1956, again an advance man on Nixon's 1960 presidential campaign, and managed Nixon's 1962 run for gov of CA. When Nixon was elected President in 1968, he selected Haldeman as his chief of staff. After he left the Nixon administration in April 1973, Haldeman was tried on counts of perjury, conspiracy, and obstruction of justice for his role in the Watergate cover-up. He was found guilty and imprisoned for 18 months. Upon Haldeman's release, he returned to private life and was a successful businessman and real estate developer until his death from cancer in 1993 at the age of 67. Haldeman is credited with implementing more significant changes to White House staffing systems and Executive Branch governance and operations than any chief of staff before him or since, and it is the "Haldeman system" that presidential administrations continue to operate on today.
