Edward Emerson Barnard is first to discover a comet by photographic means.

206P/Barnard–Boattini was the first comet to be discovered by photographic means. The American astronomer Edward Emerson Barnard did so on the night of October 13, 1892. After this apparition this comet was lost and was thus designated D/1892 T1. Ľuboš Neslušan suggests that 14P/Wolf and this comet are siblings which stem from a common parent comet.
