August 20

Team representatives met at the Hupmobile auto showroom in Canton on August 20, 1920, to form the American Professional Football Conference. The new league included franchises such as the Dayton Triangles, Decatur Staleys, and Chicago Cardinals. Organizers established rules for player contracts, scheduling, and revenue sharing to bring stability to the often-chaotic sport. In 1922, the conference was renamed the National Football League, paving the way for professional football's rise in American sports culture. The NFL would grow into one of the world's most popular and lucrative sports leagues, influencing television broadcasting and national entertainment. This founding meeting in Canton laid the groundwork for a century of gridiron tradition and competition.

Lou Gehrig of the New York Yankees belted his 23rd grand slam against the Boston Red Sox at Yankee Stadium. This milestone made Gehrig the all-time leader in career grand slams. His combination of power and consistency defined his Hall of Fame career and endeared him to baseball fans worldwide. Gehrig's 23-grand-slam record remained unsurpassed until Alex Rodriguez recorded his 24th in 2013. Known as the 'Iron Horse' for his durability, Gehrig continued to excel until his career was cut short by amyotrophic lateral sclerosis in 1939. The grand slam record highlighted both his talent and his legacy as one of baseball's all-time greats.
