Heckle and Jeckle
Jim Tyer was an animator and occasional comic book artist. He began his career in the late 1920s working for Van Bueren on 'Aesop's Fables' until the mid 1930s. He was with Fleischer and Famous Studios in the 1940s but is best known for his work for Terrytoon throughout the second half of the 1940s and the 1950s ('Tom Terrific', 'Heckle and Jeckle', 'Mighty Mouse'). In the early 1960s he worked for Trans-Lux on 'Felix the Cat' and 'Mighty Hercules' cartoons.
Between 1943 and 1947 Tyer was also a comic book artist, working through Sangor Studio. His work included mainly stories for ACG ('Pete Parrot', 'Ralph Rooster') and Better Publications ('City Slicker', 'Hiram Hound' and 'Rookie Policeman'), but also contributions to Fawcet ('Sherlock the Monk and Chuck') and Timely ('Casper Cat').
He continued to do comic book art during his Terrytoons years, drawing stories with 'Dinky', 'Heckle and Jeckle' and 'Mighty Mouse' for St. John Publishing.
