The official NFL history of the Philadelphia Eagles begins in 1933. The Eagles' history may be divided into eight distinct eras. In their history, the Eagles have appeared in the Super Bowl twice, but have never won. The Eagles have won three NFL Championships, the precursor to the Super Bowl, in four appearances.
The beginning era of the Eagles history, 1933 to 1939, was influenced by its owner, and then also coach, Bert Bell. After Bell ostensibly sold the team, to Alexis Thompson in 1940, the second era of the Eagles history was largely directed by their coach and future Hall of Famer, Greasy Neale.
In 1931, Philadelphia's NFL franchise, the Frankford Yellow Jackets, who had won the NFL Championship in 1926, went bankrupt and ceased operations midway through the season. After more than a year searching for a suitable replacement, the NFL granted an expansion franchise to a syndicate headed by former University of Pennsylvania teammates Lud Wray and Bert Bell. Bell and Wray had previously played football together on the "Union Club" squads, the Union Club of Phoenixville in 1920 and the Union Quakers of Philadelphia in 1921.
In exchange for an entry fee of $2,500, the Bell-Wray group was awarded the assets of the failed Yellow Jackets organization. Drawing inspiration from the insignia of the centerpiece of President Franklin D. Roosevelt's New Deal, specifically the National Recovery Act's "blue eagle," Bell and Wray named the new franchise the Philadelphia Eagles. Neither the Eagles nor the NFL officially regard the two franchises as the same, citing the aforementioned period of dormancy. The Eagles simply inherited the NFL rights to the Philadelphia area. Further, only a single player from the 1931 Yellow Jackets ended up with the 1933 Eagles.
