 Wilson and his chief, Col. Joseph F. Siler, greatly increased the number of laboratories in use.This exposed thousands of doctors to the use of laboratories in medicine and they returned home to demand laboratories in their hospitals.In the 1920s, Wilson married Maud Mellish [editor of Mayo Clinic's publications] and together they wrote the "Sketch of the History of the Mayo Clinic and the Mayo Foundation" anonymously in 1926.
