Who was the employer of the cartoonist who drew "Little Nemo"?
Winsor McCay:  He is best known for the comic strip "Little Nemo" (1905–14; 1924–26) and the animated film "Gertie the Dinosaur" (1914). Gertie the Dinosaur:  McCay's employer William Randolph Hearst later curtailed McCay's vaudeville activities, so McCay added a live-action introductory sequence to the film for its theatrical release.
