Charles Horace Mayo

Charles Horace Mayo (July 19, 1865 – May 26, 1939) was an American medical practitioner and was one of the founders of the Mayo Clinic along with his brother William James Mayo, Augustus Stinchfield, Christopher Graham, E. Star Judd, Henry Stanley Plummer, Melvin Millet, and Donald Balfour.
Career.
Charles graduated from the medical school of Northwestern University in 1888 and joined his father, William Worrall Mayo, and older brother, William James Mayo, in their private medical practice in Rochester, Minnesota.
The Mayos' first partner was Augustus Stinchfield, who was hired by William Worrall Mayo. Once in place as a partner in the private practice, W. W. Mayo retired at age 73. The private practice became the not-for-profit Mayo Clinic in 1919. At that point, the remaining partners went on salary, and the Mayo Properties Association was established. The world's first "integrated group practice" was established by the seven partners and staff.
The Mayo Clinic came to be regarded as one of the foremost medical treatment and research institutions in the world. Within Mayo's lifetime, it registered one million patients.
The idea of medical specialization was developed by this group of medical pioneers. A close and enduring relationship between the Mayo Clinic and the University of Minnesota Medical School developed. C. H. Mayo specialized in surgery of the thyroid and nervous system.
He was also responsible for the clinic's ophthalmic patients until 1908. He and early partners insisted on sterile conditions in the operating room, and that was one of many factors that contributed to the medical practice's early surgical successes.
Personal life.
Charles Mayo's wife was Edith Graham, of Rochester, MN, whom he married in 1893. He earned a Distinguished Service Medal for his service in WWI and afterwards in the U.S. Army's Officers' Medical Reserve Corps, eventually rising to the rank of Brigadier General. He belonged to the Episcopal church.
Charles H. Mayo was engaged in numerous civic organizations. He was a regent and later, president of the American College of Surgeons. He was a professor of surgery at the University of Minnesota, active there and nationally in both Alpha Kappa Kappa and Sigma Xi fraternities. He was a Freemason, and member of Rochester Lodge #21 of the Grand Lodge of Minnesota, AF&AM, a Knight Templar, Scottish Rite Mason and Shriner, a Kiwanis, and was active in numerous other professional, civic and social clubs.
Legacy.
Mayo retired in 1930 and died of pneumonia in 1939 in Chicago, Illinois. His two sons Charles William Mayo and Joseph Graham Mayo both worked at the clinic. Joseph Graham Mayo was killed in November 1936 in an accident when a train hit his car killing him and his hunting dog, Floosie. Mayo and his dog were buried in the same casket. A grandson, Charles Horace Mayo II, served a residency at the clinic.
The United States Postal Service released a stamp on September 11, 1964, depicting Charles Horace Mayo and his brother.
