The original Bethlehem Steel F.C. was one of the most successful early American soccer clubs; the club was sponsored by the Bethlehem Steel Corporation and played from 1907 to 1930. The club won league championships in two semi-professional leagues, the AAFBA and the NAFBL. For the inaugural 1921–1922 season of the professional American Soccer League, Bethlehem Steel F.C. moved to Philadelphia and competed as the Philadelphia Field Club. The team won the first American Soccer League championship, but moved back to Bethlehem and reverted to its original name. Three other franchises also competed as the Philadelphia Field Club, giving Philadelphia continuous representation in the ASL between 1921 and 1929 (although the second incarnation of Philadelphia Field Club changed its name to the Philadelphia Celtic for one season). During the 1924–1925 season, Fleisher Yarn joined the ASL, giving Philadelphia two teams. Excluding the first incarnation of the Philadelphia Field Club, the Philadelphia ASL teams experienced little success. The ASL was one of the most popular sports leagues in the country before it dissolved due to the onset of the Great Depression and disagreements with the United States Football Association and FIFA. After returning to Bethlehem, Bethlehem Steel F.C. won a second ASL championship in 1927, and then played in the Eastern Professional Soccer League from 1928 to 1929, winning the league championship in both seasons. The EPSL and ASL merged after the 1929 season, but Bethlehem Steel FC folded in 1930 and the ASL collapsed in 1933. Bethlehem Steel F.C. won the US Open Cup five times, which remains a record (shared with Maccabi Los Angeles). The club also won the American Cup six times. Hall of Fame Bethlehem Steel players include Jock Ferguson, Robert Millar, Harry Ratican, Tommy Fleming, and Archie Stark, whose international record of 70 goals in one season stood for 87 years before it was broken by Lionel Messi in 2012. In 2013, the Philadelphia Union unveiled a third uniform that pays homage to Bethlehem Steel F.C.
