Born in New York City, Jackson began at the age of seventeen as a clarinetist, but quickly changed to bass.
Jackson performed and/or recorded with Louis Armstrong, Raymond Scott, Jan Savitt, Henry Busse, Charlie Barnet, Oscar Pettiford, Charlie Ventura, Lionel Hampton, Bill Harris, Woody Herman, Gerry Mulligan, Lennie Tristano and others. He is perhaps best known for his spirited work both with the Herman bands, and as a leader of his own bands, big and small.
In the 1950s, Jackson worked as a studio musician, freelanced, and hosted some local children's TV shows: Chubby Jackson's Little Rascals, which was seen weekday mornings on WABC TV Ch. 7 in NYC from Monday March 23, 1959, to Friday July 14, 1961, and The Chubby Jackson Show, Saturday afternoons on WABC TV Ch.7 from July 22, 1961, to August 5, 1961.
Jackson hosted his last two children's TV shows for WOR TV Ch.9 in NYC Space Station Nine, which was seen weekday evenings from Monday January 1, 1962, to Friday January 26, 1962, and he briefly served as the fourth and last emcee of WOR TV's Looney Tunes Show/The Chubby Jackson Show weekday afternoons. The last series was seen from Monday January 12, 1962, to Friday June 14, 1962.
