content: 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.
