Steve Allen, American actor, television personality, game show panelist, and talk show host (b. 1921)
Stephen Valentine Patrick William Allen (December 26, 1921 – October 30 or 31, 2000) was an American television personality, radio personality, musician, composer, actor, comedian, and writer. In 1954, he achieved national fame as the co-creator and first host of The Tonight Show, which was the first late-night television talk show.

Though he got his start in radio, Allen is best known for his extensive network television career. He gained national attention as a guest host on Arthur Godfrey's Talent Scouts. After he hosted The Tonight Show, he went on to host numerous game and variety shows, including his own The Steve Allen Show, I've Got a Secret, and The New Steve Allen Show. He was a regular panel member on CBS's What's My Line? and, from 1977 until 1981, he wrote, produced, and hosted the award-winning public broadcasting show Meeting of Minds, a series of historical dramas presented in a talk format.

Allen was a pianist and a prolific composer. By his own estimate, he wrote more than 8,500 songs, some of which were recorded by numerous leading singers. Working as a lyricist, Allen won the 1964 Grammy Award for Best Original Jazz Composition, for "Gravy Waltz," for which he wrote the lyrics. He also wrote more than 50 books, including novels, children's books, and books of opinions, including his final book, Vulgarians at the Gate: Trash TV and Raunch Radio (2001).

In 1996 Allen was presented with the Martin Gardner Lifetime Achievement Award from the Committee for Skeptical Inquiry (CSICOP). He has two stars on the Hollywood Walk of Fame and a Hollywood theater named in his honor.
