J.Stuart Blackton was a film producer and director; he is seen as one of the pioneers of the animation industry. In 1906 Blackton made the first animated film called "Humorous Phases of Funny Faces." Blackton drew faces on a blackboard and then photographed them on film, these films were then run sequentially to the faces of the characters he illustrated. James Stuart Blackton was originally a journalist for the New York world, during this point, he was asked to interview Mr. Thomas Edison. While conversing, Blackton had made some sketches that ultimately impressed Edison which started his career in motion picture camera.
It could be argued that Blackton's creation in that time was not animated cartoons in the truest but rather based on stop motion techniques. Blackton's success ended in vain, due to a lack of motivation and Blackton not publishing his work.
Emile Cohl found his idea of taking part in animation from the success of "The Haunted Hotel" which was directed by J. Stuart Blackton, Cohl had studied this film frame by frame picking up every detail to, therefore, discover the techniques of animation. In 19098 Cohl produced the animated film "Fantasmagorie" as a result of what he had learned from Blackton's success. This movie was credited as the first fully animated film ever made. The film consisted of 700 hand drawn drawings. Many of Cohl's work had received a significant amount of reviews which were both negative and positive.
From this, it could be argued that both Blackton and Cohl are as important as each other as Blackton's lack of hard work led to Cohl seeing something Blackton didn't see in his own work. However, the fact that Blackton had created such work meant that if he didn't the idea would not have come to Cohls attention.
On the other hand, it could be argued that other people contributed to playing a significant part in revolutionizing the animation industry. For example, Windsor McCay who was an American animator and was famous for the creation of "Gertie the Dinosaur" which was an interactive sequence whereby McCay had been giving orders to an educated dinosaur
In conclusion, it could be argued that there was not only one pioneer that pushed the animation industry but rather many animators that collectively played their part in aiding the growth of the animation industry helping it become so evolved and significant in this present time.
