The bulk of the material consists of mimeographed notes on lectures and procedures of the Cleveland Clinic Hospital in the early 1920s. It also contains one early unpublished paper by Dr. Johnson, "Function of Gall Bladder and Experimental Studies on the Extra Hepatic Biliary System in Regard to the Meltzer-Lyons Test," a number of photographic and microscopic slides, a heavily annotated copy of Futcher's Outlines of Diagnosis from Dr. Johnson's medical school days, and copies of inscriptions by Dr. George Crile and others from his books.
William Oscar Johnson was born in Winchester, Kentucky and graduated from Kentucky Wesleyan College (1915) and the Johns Hopkins University of Medicine (1920).
Following residencies in surgery at Lakeside Hospital and the Cleveland Clinic Hospital, he joined the faculty of Western Reserve and then in 1927 came to the University of Louisville as an instructor in gynecology. He served on the faculty for thirty years, published numerous scientific articles, and was elected the first president of the Kentucky Obstetrical and Gynecological Society in 1948.
