Dr. Charles Denison was a prominent Denver physician. He was a Professor of Diseases of the Chest and Climatology at the University of Denver (1881-1885) and conducted groundbreaking research in climate and tuberculosis. Dr. Denison also invented a stethoscope that became a standard in the early 20th century. In 1924, his wife Ella Strong Denison donated the funds to build a new medical library in his honor. The Charles Denison Memorial Library, located on the 9th Avenue University of Colorado Health Sciences Center campus, served as the health sciences library until 2007 when the University moved to the Anschutz Medical Campus.

Located on the First Floor of the Strauss Health Sciences Library.
