Grunow, William
The “Wm. Grunow / New York” inscription on this spectrometer is that of William Grunow (1830-1917), a German craftsman who arrived in the United States in 1849. In 1873, now living in New York, Grunow announced his willingness “to execute all orders for philosophical instruments.” Grunow moved to West Point in 1881, and became custodian of the astronomical observatory at the U.S. Military Academy.
