- Bausch & Lomb introduced their Large Student’s Microscope in 1877, selling it for $90. Ernst Gundlach, a Prussian immigrant who had become superintendent of the firm’s newly established microscope department in 1876, was largely responsible for the form. This example is of that sort. It is a compound monocular with coarse and fine focus, rectangular stage, trunnion, sub-stage aperture ring with three diaphragms, sub-stage mirror, and curvaceous base. The body and tube are nickel-plated brass; the stage is heavy glass; the base is black iron. The inscription on the tube reads “BAUSCH & LOMB OPTICAL CO. ROCHESTER, N.Y.” That on the arm reads “Pat. Oct. 3. 1876.”
