Gertie, the Dinosaur is a 1914 American animated short film by Winsor McCay. Although not the first animated film, as is sometimes thought, it was the first cartoon to feature a character with an appealing personality. The appearance of a true character distinguished it from earlier animated "trick films", such as those of Blackton and Cohl, and makes it the predecessor to later popular cartoons such as those by Walt Disney.
The film was also the first to be created using keyframe animation. The film has been selected for preservation in the United States National Film Registry, and was named #6 of the 50 Greatest Cartoons of all time in a 1994 survey of animators and cartoon historians by Jerry Beck.
