Henry Draper (1837-1882) was a young physician who, in the early 1860s, built a large reflecting telescope, installed it in an observatory at his parents’ house in Hastings-on-Hudson, New York, and took a series of amazing images of the moon. This example is on opaque glass, with the emulsion side exposed, and is slightly different from the one that was printed and widely distributed.
