Erie County was formed from parts of Allegheny County on March 12, 1800. On May 27, 1861, tracks owned by the Atlantic and Great Western Railroad intersected with those of the Sunbury and Erie Railroad and was called the "Atlantic and Erie Junction". Land at the junction was owned by Hiram Cory, who sold a portion to the Atlantic and Great Western in October 1861. The railroad built a ticket office at the junction and named it for Cory, but through a misspelling it became Corry. The combination of railroad growth and the discovery of oil in nearby Titusville contributed greatly to Corry's development. This boomtown was chartered as a borough in 1863 and designated as a city in 1866. Industry has played a big part in Corry's growth, and the Corry Area Historical Society maintains a museum where one of the Climax locomotives is on display. Corry has been named a Tree City USA for seven consecutive years. The Corry Armory was listed on the National Register of Historic Places in 1991.
