Wollensak Optical Co. (Rochester, NY)

Automatic Shutter - c. 1902

Notes:  In 1899, Andrew Wollensak, who had worked on the Iris Diaphragm Shutter, left Bausch & Lomb and, with his brother, John, and an investor, Stephen Rauber, founded the Rauber & Wollensak Optical Co.  When Rauber died in 1891, the name was changed to the Wollensak Optical Co.  Both the Automatic and the Regular shutters were in the 1903 Wollensak catalog.
