- Description
- This spectroscope has a collimator with slit, a viewing telescope, and a brass stand with iron trileg base. One quarter of the horizontal circle is graduated to 20’ and read by Vernier. The original prism has been lost. The “John Browning 63 Strand, London” inscription on the circle refers to John Browning (ca. 1831-1925), the first important English spectroscope maker. Browning moved to that address in 1872, sold his firm in 1900, and termed this a Student’s Spectroscope.
- The “J.W. Queen & Co. PHILADELPHIA” inscription on a tag refers to an American firm that was selling Browning instruments by 1874.
- This came from Baldwin-Wallace University in Berea, Ohio, but whether it was originally owned by the Baldwin Institute or the German Wallace College is not yet known.
