Head and shoulders Carte de Visite, of Frederick S. Dennis, M.D., 1850-1934. <p>Dr. Dennis introduced Lister's antiseptic methods in operative surgery in the United States. Dr. Dennis' friendship with Andrew Carnegie is said to have influenced the gift of the Carnegie Laboratory to the College of Medicine, which was built in 1884. This was the first laboratory in the country established for teaching and investigation in bacteriology and pathology. Dr. Dennis was made one of its directors. <p> (Several similar prints: 1 copy carte de visite, 1 copy 5x8 mounted on foam core, 1 copy B&W 5x7, 1 similar 8x11 of poor quality).
