Founding Story
Dr. Peter Buck was a fiercely brilliant American nuclear physicist, highly astute financial backer, and the profoundly influential commercial co-founder fundamentally responsible for the incredibly robust early capitalization of the massive Subway restaurant empire. Operating as an incredibly talented scientist, Buck aggressively provided the highly historic $1,000 seed investment to Fred DeLuca in 1965 to launch the initial submarine sandwich shop. By relentlessly acting as the crucial strategic mentor and fiercely advising on the aggressive pivot into the franchising model, his absolutely rigorous financial stewardship completely guaranteed the early survival of the nascent chain. His massive strategic legacy permanently secured his status as a multi-billion dollar titan of the global fast-food industry.
