San Francisco 49ers
The team was founded in 1946 as a charter member of the All-America Football Conference (AAFC) and joined the NFL in 1949 when the leagues merged. The 49ers were the first major league professional sports franchise based in San Francisco. The name "49ers" comes from the prospectors who arrived in Northern California in the 1849 Gold Rush. The team is legally and corporately registered as the San Francisco Forty Niners. The team began play at Kezar Stadium in San Francisco before moving across town to Candlestick Park in 1970 and then to Levi's Stadium in Santa Clara in 2014.
Kezar Stadium
During the reconstruction, the field and track configurations were shifted several degrees counterclockwise, to move the stadium away from Frederick Street. The evidence for this can be seen by examining photos of the tunnel entrance at the east end of the field, which used to be exactly on the long axis of the track. A replica of the original concrete arch bearing the name "Kezar Stadium" was built on the west side of the stadium as a tribute to the original structure. A plaque of NFL Hall of Famer Bob St. Clair, a San Francisco native who played 11 pro seasons (1953–63) with the 49ers, plus his high school (S.F. Poly) and most of his college career (USF) at Kezar Stadium, is built into the replica arch.
