Answer 2

History of the Mayo Clinic.

It's also a story of an extraordinary family -- Dr. William Worrall Mayo, a frontier doctor, and his two sons, Dr. William J. Mayo and Dr. Charles H. Mayo, and the great institution they built, Mayo Clinic. It's the story of a deadly tornado and the partnership that evolved between the Mayo family and the Sisters of Saint Francis.
