Microscope

Description
This is a Van Heurck Model B compound monocular. William Watson & Sons designed the form in 1891 at the suggestion of Henri van Heurck, a noted Belgian microscopist, and sold it as suitable for photography and high-power work. It has coarse and fine adjustment, mechanical stage with centering screws, sub-stage mirror, tripod foot, wooden case, and several eyepieces and objectives. The inscription reads “W. WATSON & SONS / 313 HIGH HOLBORN / LONDON” and “3678.”
Julius F. Stone saw the Watson display at the Columbian Exposition held in Chicago in 1893 and bought this example soon thereafter. In 1943 he gave it to Thomas Henry Langlois, a biologist who would become director of the Franz Theodore Stone Laboratory on Gibraltar Island in Lake Erie. Dr. Langlois’ daughter, and her husband, gave it to the Smithsonian in 1975.
