Otto Messmer (August 16 1892 - October 28 1983) was an 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.
