This is a compound binocular with quadruple nosepiece, large square mechanical stage, inclination joint, V-shaped base, and wooden case with extra lenses. The inscription reads “Bausch & Lomb Optical Co. / U.S.A. / Rochester, N.Y.” The stage is a Spencer. The base is inscribed “ATLANTEX & ZIELER CORP / DEDHAM / MASS. 326-7410.”
This microscope was used at the Worcester Foundation for Experimental Biology, a facility in Shrewesbury, Ma., in which the biologist, Gregory Pincus, conducted research leading to the first oral contraceptive. Anne P. Merrill, a technician who worked with Pincus on that project, donated it to the Smithsonian.
