Wednesday marks the one hundredth anniversary of the first ring encounter between Jack Dempsey and Gene Tunney, a legendary rivalry that produced two of the most celebrated championship bouts in boxing history and stood among the grandest sports spectacles ever staged in America. Long before they crossed paths in a packed Philadelphia stadium, however, the path to heavyweight glory began in the harshest corners of early 20th-century America. Dempsey, who bridged boxing’s transformation from its rough-hewn, unregulated past into its modern golden era, emerged from extreme poverty to become one of the most charismatic and revered figures in sports history.

For the young wanderer, stepping into the ring was not a pursuit of grand athletic achievement, but a brutal effort to secure his next meal. As Dempsey later recalled of those formative years: "When you’re fighting, you’re fighting for one thing. To get money. When I was a young fellow, I was knocked down plenty. I wanted to stay down. I couldn’t. I had to collect that $2 for winning or go hungry. I had one fight when I was knocked down 11 times before I got up to win. I had to get up. I was a hungry fighter.
