Motion Picture Cartoonist and Director. Co-founder of the Terrytoons animation studio. A onetime newspaper cartoonist, Moser arrived in New York City in 1915 and learned to animate at Raoul Barré Productions, the first professional cartoon studio. The following year he joined Hearst's International Film Service, which brought popular comic strips to the screen; among the series he worked on were "Krazy Kat", "Happy Hooligan", and "Bringing Up Father". After World War I Moser began his association with producer Paul Terry, becoming a lead animator of the "Farmer Al Falfa" and "Aesop's Film Fables" cartoons at the Fables Studio. When Terry decided to leave Fables in late 1928 he persuaded Moser to join him in forming a new cartoon studio. It was Moser who got the enterprise started by bringing in a third partner, Joseph Coffman of Audio Cinema, who provided financing, facilities, and a distribution deal with Educational Pictures (which in turn released through Fox, later 20th Century-Fox); the firm was originally called Moser-Terry-Coffman. By 1930 Coffman had sold his interest and the studio was renamed Terrytoons. As chief director and supervising animator Moser helped create over 200 Terrytoons shorts; among the young talents he trained were future animation legends Art Babbitt and Bill Tytla. Moser was known as a "speed wizard" among animators, valued for the prodigious rates at which he could crank out drawings; he was often responsible for nearly half the footage of each cartoon. (He agreed that he "sweat blood" over his work). Not all his colleagues were impressed with his abilities. Terrytoons veteran Mannie Davis said of him, "He was a very clever guy with his pencil, but he wasn't funny. He was very, very fast, could make the stuff move nicely in those days. But he really had no sense of humor; he couldn't get a gag over. We were always at odds about that". Moser himself was at odds with Terry over the latter's refusal to improve the quality of their cartoons by using color and developing regular characters. In 1936 Educational announced it would cease distributing Terrytoons, and Moser, believing this would put the studio out of business, agreed to Terry's hasty offer of a buyout. One week later Terrytoons signed a new deal with Educational with a promise to upgrade its product, and went on to greater fame as the home of Mighty Mouse and Heckle and Jeckle. Moser subsequently sued Terry and Educational, claiming the value of the company had been misrepresented to him so his partner could gain total control. He lost the case and never returned to animation. In later years he worked as a commercial illustrator, landscape painter, and art historian, being an authority on the 19th Century Hudson River School.
