Ub Iwerks was born in 1901 in Kansas City. His father Eert Ubbe was an immigrant from Germany. In 1919 he met Walt Disney the first time. Some months later, Disney founded his first studio. Ub Iwerks was his first artist, and at this time the only one. Iwerks was called "the fastest animator" of Hollywood, because he could drew more than 700 pictures a day. In fact, he finished the first Mickey Mouse cartoon which was produced in just two weeks.
