Growing up in Robbinsdale, Minn., Gagne was a three sport athlete in high school. While he also played baseball and football, his true skill was in wrestling, where he won multiple state championships. He then went on to the University of Minnesota, where he continued to play football and wrestle. He left after one year to join the Marines at the end of World War II, but returned to finish his college career a few years later. When his amateur wrestling career was over, Gagne had four Big Ten Wrestling Championships, two NCAA Wrestling Championships, the 1949 AAU Wrestling Championship and a slot on the 1948 United States Olympic team on his resume.

Gagne debuted as a pro in 1950 and won several regional championships throughout the 1950s before heading to the newly formed American Wrestling Association in 1960. In August 1960, he was awarded his first AWA World Heavyweight Championship when the first recognized champion, then-NWA World Heavyweight Champion Pat O'Connor, failed to defend the championship against Gagne.
