On August 21, 1883, the [[1883 Rochester Tornado|Great Tornado]] demolished much of Rochester, leaving 37 dead and approximately 200 injured. As there was no medical facility in the immediate area at the time, Mayo and his [[Mayo Clinic#Early years|two sons]] worked together to care for the wounded. Donations of US$60,000 (US$1,932,562 in 2022) were collected and the [[Sisters of Saint Francis of Rochester, Minnesota|Sisters of St. Francis]], assisted by Mayo, opened a new facility named [[Saint Marys Hospital (Rochester)|St. Marys Hospital]] in 1889.<ref>{{cite web |url=http://www.mayoclinic.org/tradition-heritage/tornado-saint-marys.html |title=Tornado Strikes Rochester |publisher=Mayo Foundation for Medical and Educational Research}}</ref>
