In 1965, a 17-year-old boy named Fred DeLuca opened up a sandwich shop to earn money for college with help from his family friend Dr. Peter Buck. This restaurant would later become Subway, but the sub shop had an earlier name that was not nearly as successful.

Dr. Buck initially named the restaurant Pete's Super Submarines after himself, but this posed a problem when the pair advertised on the radio: when DeLuca said "Pete's Submarines," listeners thought he was saying "Pizza Marines" because of his New York accent. The name was changed to Subway in 1968, ending that issue.

With the new Subway name, Fred DeLuca and Dr. Peter Buck continued to branch out with new locations in the United States and other countries. Fast-forward to today, and the restaurant that began as a way to save for college is one of the most successful fast-food chains in the world.
