If you needed medical care in Southeast Minnesota during the time of President William McKinley — 1899 to be exact — you came to Saint Marys Hospital, the early ancestor to today's Mayo Clinic Hospital — Rochester, Saint Marys Campus.
The map below shows Saint Marys Hospital building construction through 1980. The gray-shaded buildings south of the Domitilla Building labeled "1889" and "1894" are photographed. These buildings have since been razed for new facilities, as has the smokestack at right in the photo. This is not the same smokestack that remains on the Saint Marys Campus today.
In 1899, Gertrude Booker Granger, M.D., who often was considered the first woman physician to join the Mayo practice, was working on staff. She joined in January 1898, assisting Charles Mayo, M.D., in the care of diseases of the eye, ears, nose, and throat. The Mayo brothers were next-door neighbors, living on what is now Fourth Street Southwest. Dr. Charlie’s house was where the Opus Building now stands; William Mayo, M.D., lived next door at a site formerly occupied by the College Apartments and now a Mayo parking lot.
