The story
In 1850, a group of Jesuits left Europe in response to Bishop John Timon's call for a Catholic institution to serve European immigrants settling in Western New York. The Jesuits founded Buffalo's first Catholic college and named it after St. Peter Canisius, a 16th-century Jesuit theologian, scholar, evangelist, and educator.
Canisius High School was opened next to St. Michael's Church in September 1870 as part of Canisius College. It moved to Washington Street in 1872. In 1912 there were 379 students. In 1919, Fr. Robert Johnson was named as the first rector. The school was chartered separately from the college in September 1928.
