The letters "GSH" on the left sleeve of the Chicago Bears uniform are the initials of the late George S. Halas. The letters were added to the jersey in 1984 in honor of their long-time owner.
Nicknamed "Papa Bear," Halas founded the organization in 1920, when they were known as the Decatur Staleys, and remained the Bears' owner until his death on October 31, 1983. During this period, Halas also served as a player for 10 seasons and head coach for 38 before stepping away from the sidelines following the 1967 season. He was inducted into the Pro Football Hall of Fame in 1963.
