Born in New York City, Wendell served in the United States Army Air Corps during World War II and graduated from Fordham University with a degree in speech. He began his radio career in summer of 1947 at WHAM in Rochester, New York. He moved to WWJ Detroit where he worked in both radio and TV. Wendell returned to Manhattan in 1952 when he landed a job on the DuMont television network emceeing several shows before jumping to NBC in 1955. He was a regular on the 1955-56 version of The Ernie Kovacs Show, serving as the show's announcer, as well as a participant in sketches such as "Mr. Question Man". He also worked with Steve Allen, Jack Paar, Dave Garroway and other NBC personalities. On October 13, 1958, Wendell succeeded Jack Barry as emcee of Tic Tac Dough, until it was finally cancelled in October the following year and by December, had resumed his staff announcing position at NBC, forming part of a fraternity of network staff announcers who held lifetime contracts; his colleagues were Don Pardo, Wayne Howell, Fred Facey, Bill McCord, Roger Tuttle and Howard Reig. During the 1970s, Wendell succeeded Johnny Olson as the announcer of the syndicated To Tell the Truth from 1972–1977, after Olson left New York City to assume the job on CBS's game The New Price Is Right, based in Southern California. Wendell was also announcer for several years on Sale of the Century and the Macy's Thanksgiving Day Parade. In addition, during the years when the television networks didn't broadcast 24 hours a day, Wendell anchored a five-minute summary of the day's news—the last program NBC would air before local affiliates would sign off—on which he was heard but not seen as a network hand displayed still images or illustrations related to the brief news items. His most notable stint on television was as David Letterman's announcer, beginning partway through the short-lived morning program The David Letterman Show in 1980. He continued with Letterman as the regular announcer for NBC's Late Night with David Letterman from 1982–1993, the entirety of the show's NBC run. In addition to his duties as announcer, Wendell occasionally participated in sketches, usually playing himself. He moved with Letterman to CBS in 1993, staying as announcer on the Late Show with David Letterman. Wendell retired in mid-1995, with his last episode airing on August 18. Following a two-week hiatus, Alan Kalter succeeded him as announcer on September 4. Kalter had previously replaced Wendell as announcer for the final season of To Tell the Truth in 1977–78. Before he announced for David Letterman's Late Night, Wendell was announcer on Tom Snyder's Tomorrow Show when Snyder moved production from Burbank, California to New York. Letterman's show replaced Snyder's and kept Wendell as announcer. On the June 14, 2018 episode of The Carson Podcast with guest Robert Morton, Morton revealed that Letterman had wanted Wendell gone for ages and that Wendell was finally fired for getting caught stealing water bottles purchased by and sent out for the show's staff on multiple occasions. Wendell also appeared as a TV announcer in the movie Mr. Saturday Night, which starred Billy Crystal. Wendell's last major job was as the original voiceover announcer in Old Navy's "fashion show" commercial campaign.
