This is the previously untold story of the London Tecumsehs, an 1870s baseball team that rose to the top ranks of pro ball. The Tecumsehs of London, Ontario, were among the founding members of the International Association in 1877, the first league established to challenge the struggling National League, formed a year earlier. The team played against the top competition of the day and defeated nines from Chicago, St. Louis and elsewhere. They became the first champions of the International Association when they defeated Pittsburgh with the arm of Fred Goldsmith, one of the first curveball pitchers. This is also the story of the International Association, the only one of the six leagues challenging the primacy of the National League that has never been accorded major league status. To this day it has been relegated to minor league status to the detriment of some of the pioneer players in the game.
