Mayo, Charles Horace

Mentioned in the 1953-01-08-03 Minutes of the Pima County Medical Society, 1904-1954: [Dr. Manning] "...made the suggestion that it might also be better to have a Program Committee which will work for two years, stating one instance of having contacted Dr. Charles Mayo who could not come this year but might do so the next year, but that he, Dr. Manning, had not felt free to make arrangements for the next Program Chairman." Most likely a reference to one of the Mayo brothers of Mayo Clinic fame (William J. and Charles H.)? Both brothers had died in 1939 – almost 14 years before.
