When Don graduated from High School in 1943, World War II was raging, so he joined the Navy. He was soon shipped off to the Pacific Theater of Operations, with the 7th Fleet. While in the Navy, Don got married to his first wife, Maxine. Don tattooed her name on his left arm. The couple had a daughter, Linda Lee, but their marriage didn't last, and they divorced.
Returning home after the war ended, Don married his second wife, Doris, in 1947, when she was two months pregnant. Seven moths later, they had a son, Larry. Don became a full-time driver for United Parcel Service, and began earning extra money by doing art jobs and pinstriping on cars.
He soon landed a job as an "in-betweener" at Disney Studios, creating drawings that came "in-between" shots done by other animators. But the nature of this job stifled Don's wild, independent streak, and he quit after just two days! He went back to UPS, who paid him more anyway. Below, Don and his UPS truck.
