Bernard Kalb, a veteran correspondent for CBS, NBC and The New York Times, died on Jan. 8 at his home in North Bethesda, MD. He was 100.

He reported for The Times from 1946 to 1962, for CBS during the next 18 years, and as NBC’s

State Department correspondent from 1980 to 1985. Then, for nearly two years, he served in the Reagan administration’s State Department.

Mr. Kalb accompanied President Richard M. Nixon on the trip to China that proved to be a major step in the normalization of relations between the two nations. He also made virtually every overseas trip with Henry A. Kissinger, Cyrus R. Vance, Edmund S. Muskie, Alexander M. Haig Jr., and George P. Shultz during their tenures as secretary of state.

For six years starting in 1992, Mr. Kalb was the moderator of the weekly CNN program “Reliable Sources,” which analyzed the news media’s objectivity and interviewed print and broadcast journalists. He continued lecturing on journalism and foreign affairs into his 90s, including as an occasional panelist on “The Kalb Report,” a televised series of live talks hosted by his brother, Marvin Kalb, at the Washington National Press Club.
