[12] When the United States entered World War II in 1941, Garroway enlisted in the U.S. Navy, serving as a line officer.
[13] While stationed in Honolulu, he hosted a radio show when he was off duty, playing jazz records and reminiscing about the old days back in Chicago.
[8][15] One oddity Garroway introduced on his radio shows was having the studio audience respond to a song number not by applauding, but by snapping their fingers.
[23] Garroway worked on the air at WCBS radio in 1964 and briefly hosted the afternoon rush-hour shift at KFI in Los Angeles in late 1970 and early 1971.
In 1960, reviewer Richard F. Shepard of The New York Times wrote, "He does not crash into the home with the false jollity and thunderous witticisms of a backslapper.
Along with Arthur Godfrey, Arlene Francis, Steve Allen, and Jack Paar, Garroway was one of the pioneers of the television talk show.
[31] Garroway, Studs Terkel, and Hugh Downs all hosted relaxed, garrulous, extemporaneous shows in that city in the early 1950s.
Earlier radio and television voices spoke with an authoritative "announcer's" intonation, resembling public oration, often dropping about a musical fifth on the last word of a sentence.
Pioneering NBC president Sylvester "Pat" Weaver chose Garroway as the host of his new morning news-and-entertainment experiment, the Today show, in 1952.
[33] Though initially panned by critics, Garroway's style attracted a large audience that enjoyed his easygoing presence early in the morning.
[34][35] His familiar "cohost", a chimpanzee with the puckish name of J. Fred Muggs, did not hurt his genial manner, but his concurrent seriousness in dealing with news stories and ability to clearly explain abstract concepts earned him the nickname "The Communicator" and eventually won praise from critics and viewers alike.
[39] Garroway took Today to various locations during his tenure - Paris in 1959 and Rome in 1960; car shows and technology expos; plays and movies; and aboard an Air Force B-52 for a practice bombing run.
Through television, Garroway gave viewers access to a variety of people that included politicians, writers, artists, scientists, economists, and musicians.
Toward the end of his professional career, he began to have disagreements with staff members; some days, Garroway would disappear in the middle of the Today broadcast, leaving colleagues to finish the live program.
[1][45][46] In late May 1961, Garroway resigned, announcing his intention to leave Today—either at the end of October when his contract was finished or sooner, if possible — to spend more time with his children.
[52] In April 1969, Garroway launched a daytime talk show on WNAC-TV, Tempo Boston, which he hoped would be picked up for national syndication.
Stations in New York and Philadelphia agreed to pick up the show, but by early 1970, the small-scale syndication ended and Tempo was cancelled.
[5] After leaving the Boston airwaves, Garroway traveled to Southern California, hosting a music-and-talk show on KFI radio in Los Angeles.
[6][53] While in Los Angeles, Garroway began to take acting workshops; he had a role in an episode of the Western series Alias Smith and Jones as a judge in 1972.
[61] Garroway was very interested in astronomy, and during a tour of Russian telescopes, he met his third wife, astronomer Sarah Lee Lippincott.
Garroway, who had recently undergone drug rehabilitation for an amphetamine addiction, appeared to be cheerful and in good spirits during the show.
[7][9] Garroway's son Michael said that his father had been experiencing complications from his heart operation and he had "unfortunately succumbed to the traumatic effects of his illness".
His colleague Jack Lescoulie, news editor Frank Blair, and former consumer reporter Betty Furness offered tributes on the show.
