HOLDEN, EDWARD SINGLETON. 1846-1914.
The Moon at 23 days and 8 hours, from Lick Observatory, Mount Hamilton, CA, July 28, 1891, albumen contact print, 9¾ x 7½ inches (250 x 195 mm), faintly captioned in negative (in part "E.S.H. & W.W.C."), titled on verso in ink.
Holden was the first director of the Lick Observatory, from 1888 until the end of 1897. Prior to then, he had been president of the University of California. The W.W.C. with whom Holden made this photograph was the young William Wallace Campbell [1862-1938], who had only just joined the Observatory but would also go on to be its director.
