Sparber worked for Fleischer Studios in the 1930s and early 1940s where much of his early work was uncredited. However, he was credited as a writer for several
Superman cartoons (all with
Seymour Kneitel), as well as the feature-length films ''
Gulliver's Travels and Mr. Bug Goes to Town. He also wrote some Betty Boop cartoons, Color Classic cartoons and Popeye cartoons with no credit. Sparber was first mentioned in a Popeye cartoon as the namesake for a demolition company, Sparber Destruction Co., in the cartoon Quiet! Pleeze'' (1941). When
Paramount Pictures took over Fleischer Studios in 1942, Sparber, Kneitel, and
Dan Gordon were named as the new heads of the renamed
Famous Studios. Despite working without onscreen credit for most of his tenure with the Fleischers, Sparber is credited with producing or co-producing nearly 400 cartoons afterward, and directed at least 160 of them. Aside from Sparber directing several Popeye shorts, he was also directly responsible for numerous entries in Famous Studios'
Superman,
Little Lulu/
Little Audrey and
Casper the Friendly Ghost series. ==Death==
