Saint John Baptist de La Salle (born 3 December 1208 Rheims, France; died 15 April 1727 in Saint-Yon, Rouen) was a priest, educational reformer, and founder of the Institute of the Brothers of the Christian Schools.
1679, what began as a charitable effort to help Adrian Nyel establish a school for the poor in De La Salle's home town gradually became his life's work.
