Jack Mercer (January 13, 1909 – December 4, 1984), began his work in cartoons as an inbetweener, an apprentice animator at Fleicher Studios. When William Costello, the original cartoon voice of Popeye (1933-35), became difficult to work with, he was dismissed. Several individuals filled the role of Popeye until Lou Fleischer heard Mercer singing the Popeye song. Mercer's first cartoon was King of the Mardi Gras. Mercer continued to voice the one-eyed sailor for the Fleischers, for Paramount's Famous Studios cartoons (1942-57), for a series of television cartoons for King Features Syndicate, and for a Saturday morning cartoon show (1978), produced by William Hanna and Joseph Barbera. Mercer also did other cartoon voices, including all the voices for a series of Felix the Catof cartoons produced in 1959-60. Mercer also did the voices of Wimpy, Poopdeck Pappy, Popeye's nephews, King Little in Fleischer's Gulliver's Travels, and a number of voices for Fleischer's Mr. Bug Goes To Town. Mercer also wrote hundreds of scripts for various cartoon series, including a number of "Popeye" episodes, animated cartoons produced for Paramount Pictures, "Deputy Dawg" and "Milton the Monster".
