Abstract:
Christian Henry Brown, M.D., (1857-1933) was an oculist who operated the Philadelphia Optical College for over forty years. This paper provides a brief biographical sketch of C.H. Brown and a history of the Philadelphia Optical College. The Philadelphia Optical College offered attendance and correspondence courses in optometry, and claimed to have had several thousand graduates. It did not fare well in a rating of optometry schools in the mid-1920s. Brown authored several significant textbooks, most notably Optician's Manual, later retitled Optometrist's Manual.
