Answers:

1.  For several years after their marriages, the brothers and their wives were next-door neighbors.

True. Soon after Dr. Will married Hattie Damon, they built a house on College Street (today, Fourth Street SW) in Rochester, Minnesota. When Dr. Charlie married Edith Graham, R.N., they lived with Dr. Will and Hattie for about two years while their house was under construction next door. Both residences were large, wooden, Victorian-style houses, distinguishable mainly by color.

2.  Dr. Will and Dr. Charlie served a term as co-presidents of the American Medical Association. 

False. Both brothers held office as president of the American Medical Association (AMA), but they served alone and in different years. Dr. Will was president from 1906-1907 and Dr. Charlie was president from 1917-1918.

3. In 1964, the United States Mint issued a commemorative coin to honor the Mayo brothers.  

False. However, there was a commemorative “Doctors Mayo” postage stamp. U.S. Postmaster John Gronouski was the guest of honor at a ceremony to release the stamp in the lobby of the Mayo Building on September 11, 1964.
