The University of St. Michael's College is a college of the University of Toronto, founded in 1852 by the Congregation of St. Basil of Annonay, France. While mainly an undergraduate college for liberal arts and sciences, St. Michael's retains its Roman Catholic affiliation through its postgraduate divinity school. St. Michael's is most closely associated with teaching and research in the humanities. It is also known for being home to Marshall McLuhan throughout his influential career as a philosopher and communication theorist, from 1946 until his death in 1980. The Pontifical Institute of Mediaeval Studies resides within the college, while St. Michael's College School is an affiliated private preparatory school. St. Michael’s College was founded in 1852 as a Basilian college by Pierre Tourvieille, Superior General of the Congregation of St. Basil of Annonay, France. The following year, it merged with St. Mary's Lesser Seminary under the unified control of the Basilian Fathers. St. Michael's College educated pupils at three levels, operating as a preparatory school, as a liberal arts college, and as a minor seminary.
