The first animated film created by using traditional techniqe(hand-drawn) animation - the 1908 Fantasmagorie by Emile Cohl !
The more detailed hand-drawn animations, requiring a team of animators drawing each frame manually with detailed backgrounds and characters, were those directed by Winsor McCay, a successful newspaper cartoonist, including the 1911 Little Nemo, the 1914 Gertie the Dinosaur, and the 1918 The Sinking of the Lusitania.
