label: Description
content: Visitors to the Centennial Exhibition of 1876 might examine “a volume of 9 photographs (large quarto) copied at the Army Medical Museum from daguerreotypes of microscopical objects made by Professor Draper in 1850-’52.” According to an official account of this display, the “special interest attaching to these photographs is that the daguerreotypes were the first of microscopic objects made in America, and that they were made by Professor Draper by sunlight passed through a cell containing the ammonia-sulphate of copper; a method original with him which has since been found indispensable to success in photomicrography.”
