"A terrible tornado struck the city in 1883, and doctors were forced to treat its many victims under inadequate, makeshift conditions. Mother Alfred Moes, founder of the Sisters of St. Francis, proposed the building and staffing of a hospital, in which W.W. Mayo would provide the care. In 1889 St. Mary's Hospital opened with 27 beds."
