Spectroscope

Description
This is a six-prism instrument on a rectangular base. The “Wm. Grunow / New York” inscription refers to William Grunow (1830-1917), a German craftsman who, with his brother Julius, came to the United States in 1849 and went to work making microscopes. In 1873, now settled in New York, Grunow announced his willingness “to execute all orders for philosophical instruments.” In 1881 he moved to West Point, and spent the next 36 years as custodian of the astronomical observatory of the U.S. Military Academy.
