Description
This is marked “No. 9. Navicula Formosum. Copied from a Daguerreotype by Prof. J. W. Draper of New York.” The reference is to John William Draper (1811-1882), an English immigrant who did import work in several areas of science and medicine.
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.”
