Yes, Rochester is a one horse town. Rochester was selected by the Mayo brothers, because land was cheap, it had the railway, and it had good transport to a lot of major cities. That was around 1880, and they founded the world's first multispecialty clinic. They had the Catholic nuns staff the hospital since they were Irish Catholics.
They had a pal from Ireland come over the build a big hotel for families and patients to stay. That is the Kahler and it is still there. Unfortunately it has been wantonly mucked about in recent years. When I first new it fifty odd years ago, it was very much as it always was, with the Victorian grand staircase and dining room.
Mayo was founded very much on monastic principles, and actually still has that feel. The physicians often refer to themselves as men of the cloth. We did that often in the Grand Forks Clinic which was on the Mayo model.
Mayo has always had an interest beyond medicine, especially vehicles. In the early days of motoring Mayo did research on automobile maintenance. I attended a lecture from their chief librarian some years ago, and he had slides of a lot of the documents. It was absolutely fascinating. This tradition continues as they have a department developing autonomous vehicles.
I took this picture of one some years ago when they were experimenting at night.
These vehicles are now picking patients up from the Mayo building and taking them to their hotels and St. Mary's Hospital.
