Bill Tytla
Vladimir Peter Bill Tytla was one of the original Disney animators and is considered by many to be the best Disney animator that ever lived. Tytla is particularly noted for the animation of Grumpy in Snow White and the Seven Dwarfs, Stromboli in Pinocchio, Chernabog in the Night on Bald Mountain sequence from Fantasia and the title character in Dumbo.
Vladimir Peter Tytla was born on October 25, 1904 in Yonkers, New York. His Ukrainian immigrant parents reportedly recognized talent in their son and encouraged it. In 1914, when Tytla was 9, he visited Manhattan to attend Gertie the Dinosaur, an animated vaudeville act by Winsor McCay. He never forgot it, and some say it changed his life forever.
