"Casper was created in the early-1940s by Seymour Reit and Joe Oriolo. Intended initially as the basis for a children's storybook, there was initially little interest in their idea and when Reit was away on military service during the Second World War, Oriolo sold the rights to the character to Paramount Pictures' Famous Studios animation division, for which he had occasionally worked.
The Friendly Ghost, the first Noveltoon to feature Casper, was released by Paramount in 1945. In the cartoon, Casper is a cute, pudgy ghost-child, who prefers making friends with people instead of scaring them. " (Source : Wikipedia)
