After working briefly for Friz Freleng at Warner Brothers, he began working for Western Publishing in 1947, illustrating Little Golden Books, other children's books, and comic books for the Dell Comics and Gold Key Comics imprints along with the Disney Studio Program.
Bradbury began working for Disney at age 20 and was responsible for key scenes in movies like Bambi, Fantasia, and Pinocchio. Reportedly Walt Disney told Western that they didn’t need his approval for any of Bradbury’s work. Also, Bob Clampett specifically requested Bradbury to illustrate the comic book adaptation of his show Time for Beany.
According to the book Walt"s People - Volume 3: Talking Disney with the Artists who Knew Him by Didier Ghez, which presents a full reprint of an interview with Jack himself made by Klaus Strzyz in 1978, he never considered himself a "very good duck man", preferring to draw stories with Mickey and Goofy.
When Mr. Strzyz asked him about the quality of 1940s, 1950s and 1960s Disney comic stories in comparison with the 1970s ones, he answered that the then later ones were far better in terms of quality, the only exception being Bark"s old ones. Including he affirmed that he felt embarrassed when he eventually saw some of his own early works.
Although he didn"t have a very good opinion about his own work with Donald and his family, Bradbury drew important and popular stories with them, like "Family Tree". Eye problems forced Bradbury to cut back on his output after 1970, though he still continued to work on a few projects for Disney.
He died in 2004 from kidney failure.
