Jean-Pierre-François-Laforce Langevin (22 September 1821 – 26 January 1892) was born and lived his life in Quebec.

He began his studies for the priesthood at the Grand Séminaire and taught back at his old school, a vocation he continued after he was ordained priest.

His teaching and parish experience covered a number of years and were rewarding and successful.

His final position in education was principal of the École Normale Laval.

He resigned his duties in 1891 at the request of Cardinal Taschereau on behalf of papal authorities.
