from SEDS: Barnard 33, the Horsehead Nebula (http://seds.org/messier/xtra/ngc/b33.html):


E. Pickering detected IC 434 photographically in 1889, the Horsehead can be detected on a photo made on January 25, 1900 by Isaac Roberts (Roberts 1902). E.E. Barnard recognized the object in the 1910s.
[...]
The first published description of the Horsehead Nebula was given in Barnard (1913), and it was first cataloged by Barnard (1919).

Have you read this wiki article about Williamina Fleming, who was originally E.C. Pickering's maid, but went on to discover the Horsehead Nebula (and several others)?
http://en.wikipedia.org/wiki/Williamina_Fleming

The discovery was credited to Pickering incorrectly, or so it says.
Here's the 'discovery image' from 1882 (Harvard plate B2312)
