American animator, best known for his work on the Felix the Cat cartoons and comic strip produced by the Pat Sullivan studio. The extent of Messmer's role in the creation and popularity of Felix is a matter of ongoing dispute, particularly as he only laid his claim to the character after the death of Sullivan, who until that time had received the credit. However, most prominent comics and animation historians support Messmer's claim, as do the veterans of the Sullivan studio. (Wikipedia)
