Heritage Day is the celebration of the origin of the University of the Incarnate Word. In 1869, San Antonio suffered a cholera outbreak. In response to San Antonio's need for assistance, Bishop Claude M. Dubuis sent three French nuns, Sister Madeleine Chollet, Sister Pierre Cinquin, and Sister Agnes Buisson. They set up San Antonio's first hospital which is now called Santa Rosa. The building of the hospital led to an orphanage, which led to establishing a school. That school would later be what is now the University of the Incarnate Word.
