About George Halas
George Stanley Halas Sr. (February 2, 1895 – October 31, 1983), nicknamed "Papa Bear", was an American professional football end, coach, and executive. He was the founder and owner of the Chicago Bears of the National Football League (NFL), and served as his own head coach on four occasions. He was also lesser-known as a player for the New York Yankees of Major League Baseball (MLB). He is the namesake for the NFC Championship trophy. Halas was one of the co-founders of the American Professional Football Association (now the NFL) in 1920, and in 1963 became one of the first 17 inductees into the Pro Football Hall of Fame. Halas was the oldest person in NFL history to serve as a head coach, aged 72 years and 318 days when he coached the final game of his career in December 1967, a record that stood for over 50 years until Romeo Crennel became the interim head coach of the Houston Texans in October 2020, aged 73 years and 115 days. Despite a 10–1–2 record, the Staleys ended the season awash in red ink. In 1920, Halas represented the Staleys at the meeting which formed the American Professional Football Association (which became the National Football League in 1922) in Canton, Ohio.
