| Pioneer of astronomical photography, born in Prince Edward Co, Virginia, USA. He taught natural science and later physiology at the City of New York University (1860–82), but retired in order to devote himself to astronomical research. With a 71 cm (28 in) reflecting telescope he showed photographic methods to be an important means of studying the heavens. An important catalogue of stellar spectra is named after him. |
