H.R. Haldeman H.R. Haldeman H.R. "Bob" Haldeman, Nixon's chief of staff, spent 18 months in prison for his role in Watergate. A former advertising executive, Haldeman had a stern reputation as Nixon's gatekeeper and once called himself "the president's son-of-a-bitch." The controversial 18 and a half-minute gap in Nixon's Oval Office recordings included a conversation between the president and Haldeman. The chief of staff also was part of the conversation on the so-called "smoking gun" tape, in which Nixon discussed using the CIA to divert the FBI's Watergate probe. Haldeman resigned in April 1973 and was convicted of conspiracy and obstruction of justice the following year. After prison, Haldeman wrote "The Ends of Power," a memoir published in 1978. He spent his later years working as a real estate developer in Southern California. He also invested in restaurants and hotels. Haldeman died of cancer at his home in Santa Barbara on Nov. 12, 1993 -- six months before publication of "The Haldeman Diaries." He was 67. • Haldeman: Reelection Drove Nixon Policy (May 18, 1994) • H.R.
