Below is a concise history of the Wollensak Optical Company, its predecessor and its successors.
1899, July 1: Stephan Rauber (President) and brothers Andrew Wollensak (Vice President) and John Wollensak (Secretary) establish the Rauber and Wollensak Optical Company in Rochester, New York.

Andrew Wollensak, age 36, had been a machinist at Bausch and Lomb since 1883, rising to foreman of the shutter department and working with Edward Bausch on the Iris Diaphragm shutter. Andrew Wollensak’s parting from Bausch and Lomb seems to have been amicable, since within four years of his departure, Edward Bausch, Carl Lomb and other members of the Bausch and Lomb families had purchased stock in Wollensak’s new company.

1900, May 14: The Rauber and Wollensak Optical Company is incorporated under the laws of the State of New York. The initial capital stock is $40,000 at $100 per share, of which $26,500 is sold in 1900. Initial shareholders are Stephan Rauber (10 shares), Frederick Rauber (120 shares), Andrew Wollensak (120 shares), and John Wollensak (15 shares).
