Herbert G. Klein, former aide to President Nixon, community activist and onetime editor-in-chief of the former San Diego Union newspaper, died Thursday, July 2 after a battle with pneumonia. He was 91. Klein, a La Jolla resident at the time of his death, was White House director of communications during the Watergate scandal, which forced Nixon to leave office in 1974. Klein resigned the post in July of 1973. He had been associated with Nixon since 1946, when Nixon launched a California congressional bid. In 1960, he helped spearhead the first televised presidential debates between Nixon and then Sen. John Kennedy. A Los Angeles native, Klein earned a bachelor’s degree in journalism in 1940 from USC, where he met his late wife Marjorie. Klein was a Navy public affairs officer in San Diego for three years during World War II, after which he became a special correspondent for the San Diego-based Copley Newspapers. He later wrote for Copley’s Evening Tribune and San Diego Union. In 1959, he was named editor of The Union. He became Nixon’s communications director in 1968, the year Nixon won the White House. In July of 1973, amid the Watergate break-in scandal, Klein joined Metromedia Inc., a national broadcast group. He rejoined Copley as editor-in-chief in 1980.
