Academy of Our Lady and Spalding Institute were Catholic high schools across the street from each other in downtown Peoria, Illinois. The Academy (AOL), a girls' school, traced its lineage back to 1863. The Spalding Institute (SI), the boys' school, was founded in 1899 by the Franciscan Brothers of Mountbellew, Ireland, at the invitation of John Lancaster Spalding, the first Bishop of Peoria. It was one of the communities which left that religious congregation to split off and become part of the Third Order Regular of St. Francis of Penance, based in Rome, Italy.
