Newman was born on January 25, 1919, in New York City to Myron, a credit manager, and Rose (née Parker) Newman. His older brother was M.W. Newman, a longtime reporter for the Chicago Daily News. Newman married Rigel Grell on August 14, 1944. They had one daughter, Nancy, who was born on October 6, 1945.  After graduating from George Washington High School Newman attended the University of Wisconsin at Madison, serving on the staff of The Daily Cardinal and earning a bachelor’s degree in political science in 1940. He briefly did postgraduate work in American government at Louisiana State University before becoming a journalist.

Newman initially worked for the wire services: first for the International News Service as a copy boy, mostly in the Senate, and then United Press. On Sunday, December 7, 1941, the day of the attack on Pearl Harbor, he heard the news during a radio concert. When he rang the office asking if he should come in, the reply was “Hell yes!” Newman took dictation for 12 hours as United Press reporters phoned in their stories.  He served in the United States Navy from 1942 to 1945 as a signal officer, stationed first in Trinidad and then at the Brooklyn Navy Yard.[5] Following the war Newman worked as a reporter for United Press (1945–1946, primarily reporting about the State Department), before moving to the CBS News radio division (1947–1949) as assistant to Eric Sevareid.

Between 1949 and 1952 Newman worked as a freelancer, primarily for NBC News. He wrote for a number of publications and, in 1951, worked for the Marshall Plan in Greece. In 1952, Newman began to work full-time for NBC. He covered significant stories: the 1952 funeral of King George VI from the freezing battlements of Windsor Castle; Britain’s emergence as a nuclear power; and the 1956 Suez Crisis. At the same time, Newman enjoyed quirky stories; he once climbed a tree in Kensington Gardens dressed in a hunting outfit (complete with deerstalker hat and whistle) to investigate a report that ducks were nesting in trees.  Newman was an NBC bureau chief, first in Rome and then in Paris. In both assignments, diplomatic and political news (such as the twists and turns of the Cold War and the increasingly divisive anti-colonial Algerian War) vied with stories elsewhere in Europe and beyond. Newman covered the accession to power of President Charles de Gaulle in 1958. He was decorated as Chevalier of the Légion d’honneur for his coverage of de Gaulle’s funeral in 1970 and for improving the understanding of France in the United States.

Between 1961 and 1984, Newman participated in a wide variety of NBC programs, primarily for NBC News. He was a regular on the Today show and was its news anchor from July 24 to December 22, 1961, then a contributor and guest host. On Meet the Press, he was a frequent panelist and moderator.  From 1960 to 1984 Newman played a central role in NBC’s coverage of the Republican and Democratic national conventions, when gavel-to-gavel coverage was the norm. In 1968 he, John Chancellor, Frank McGee, and Sander Vanocur (dubbed “The Four Horsemen of the Apocalypse”) were fitted with state-of-the-art backpacks enabling them to roam the convention floor and conduct live interviews with delegates.  Newman specialized in reporting breaking news. In 1963, he made the first announcement on NBC Radio of President John F. Kennedy’s death. He anchored the television coverage of the 1967 Six-Day Arab-Israeli War, the 1968 assassinations of Martin Luther King and Robert Kennedy and the 1973 Vietnam ceasefire. In 1981, immediately after the assassination attempt on President Ronald Reagan, he was chosen to anchor NBC’s television coverage until full news teams were mustered.

Newman was the only journalist to interview Emperor Hirohito (Emperor Shōwa) of Japan. The interview took place in September 1975 at the Imperial Palace in Tokyo, shortly before Hirohito’s diplomatically-delicate visit to the United States. For his program Speaking Freely, he conducted more than 250 hour-long interviews with leading figures of the day between 1967 and 1976. Among interviewees were director Ingmar Bergman, zoologist Konrad Lorenz, classical guitarist Andrés Segovia, founder of Transcendental Meditation Maharishi Mahesh Yogi, boxer Muhammad Ali, and the first prime minister of Israel, David Ben-Gurion. The series was broadcast on Sunday mornings by local New York station WNBC, and syndicated to other stations.

Newman moderated two presidential debates, both of which demanded the calmness and courtesy for which he was known. The 1976 debate, between incumbent Gerald Ford and Georgia governor Jimmy Carter, was the first presidential debate since 1960 and was marred by a 27-minute loss of audio (during which the candidates stood silently by their lecterns). In 1984, President Ronald Reagan faced former Vice President Walter Mondale; when Reagan overran the time limit for his closing statement, Newman was obliged to cut off Reagan’s remarks.  Newman participated in a number of documentaries at NBC, including Japan: East is West (1961); Who Shall Live? (about kidney dialysis, 1965); Pensions: The Broken Promise (1972); Violence in America (1977); Spying for Uncle Sam (1978); Reading, Writing and Reefer (1978); Oil and American Power (1979); and The Billionaire Hunts (1981).

Newman enjoyed music and hosted summer Boston Symphony concerts from Tanglewood. He contributed to the work of the Religious Affairs Unit at NBC, and was a Broadway drama critic from 1965 to 1971. As a baseball and boxing aficionado from childhood, he also enjoyed sports broadcasting. He provided in-studio news updates in 1980, during the short-lived morning version of The David Letterman Show. Newman also showed his singing voice while on Saturday Night Live.  After leaving NBC in January 1984 Newman was in demand as an interviewer, narrator, and moderator, participating in many programs on PBS and cable networks. One series to which he was particularly committed was Congress: We the People. Beginning in 1983 Newman moderated annual televised conferences of former Secretaries of State, and conducted a series of interviews with Dean Rusk (US Secretary of State, 1961–69) for the Southern Center for International Studies in Atlanta, Georgia. He narrated a series of programs about the restoration of Michelangelo’s frescoes in the Sistine Chapel. He was in demand to play himself in films and on television. Among his film credits were The Pelican Brief, Spies Like Us, and My Fellow Americans; television appearances included episodes of Newhart, Mr. Belvedere, The Golden Girls, Wings, and Murphy Brown. He lectured extensively on the English language and the news business.  In 1990, he was a narrator for an Audio Renaissance dramatization of Ernest Callenbach’s utopian novel Ecotopia, reading the news reports of William Weston as he tours the breakaway republic.

Newman spent his final years quietly, moving with his wife to England in 2007 to be nearer to their daughter. He died of pneumonia in Oxford on August 13, 2010. The public announcement of his death was delayed for a little over a month (until September 15), to allow a period of private mourning for his family. Newman was survived by his wife and daughter.
