Born to Peter and Nora Larson. In 1915 his family moved to Salt Lake City, where he became interested in journalism and also secretly took drawing lessons.

In 1925, he entered the University of Utah, later moving to Los Angeles to look for a job in journalism and writing, unfortunately unsuccessfully. He then decided to rekindle his ambition to become an artist, and was offered a job at Walt Disney Productions in 1933, as an `in-betweener'. Later the same year, he married Gertrude Jannes (although sadly, the couple remained childless).
