Allan was inducted into the U. .Army during World War II but only served a few months, being discharged over an allergic reaction to Brazil nuts.
Sherman was his mother's maiden name.
Allan was the creator of the flop tv game show You're In The Picture, starring Jackie Gleason, that debuted on January 19, 1961 and was cancelled after thr premiere showing, with Gleason apologizing for how bad the show was the following week on national television.
It was upon the recommendation of singer/songwriter/author/comedian Allan Sherman that then comedian and later actor Bill Cosby was signed for his first live comedy recording, and by virtue of Sherman's friendship with I Spyproducer Sheldon Leonard that the latter (and co-creator/costar Robert Culp) came to appreciate Cosby's talents sufficiently to cast him in the show.
Allan Sherman's autobiography, A Gift of Laughter, was published in hardcover by Atheniuam circa 1964/1965 and as a Fawcett paperback in 1965. The book included anecdotes involving his neighbor, Harpo Marx.
