John W. Draper, 1811-1882
Scientist John W. Draper's pioneering investigations of radiant energy were critical to the emerging field of spectrum analysis. His study of the properties of light also led him to experiment with photography. In partnership with Samuel F.B. Morse in 1840, Draper opened a daguerreian portrait studio on the rooftop of the New York University building where he chaired the medical school's departments of chemistry and physiology. Created during his tenure as president of NYU's medical school, this ambrotype dates from 1856, when Draper published Human Physiology, Statistical and Dynamical -- the groundbreaking work that became the leading physiological textbook of its day.
