Spectroscope

Description
This is a small and simple direct vision spectroscope. The inscription on the case reads “WILLIAM J. HAMMER, CONSULTING ELECTRICAL ENGINEER, 26 CORTLANDT, NEW YORK.” William J. Hammer (1858-1934) worked with Thomas Edison at Menlo Park and had wide interests in electrical science and technology. By 1890 Hammer was an established consulting engineer in New York City. It is unknown how and when the spectroscope ended up in Hammer’s collection. He may have purchased it for use or it may have been given to him for evaluation.
