Microscope No. 23175 - Associated with the Laboratory of the United States Marine Hospital Service
- Description
- This medium-sized compound monocular is a Zeiss model IVa with coarse and fine focus, triple nosepiece (with three Zeiss objectives), square mechanical stage, trunnion, Abbé condenser with iris diaphragm that can shift from left to right, sub-stage mirror, horseshoe base, and wooden box with extra lenses. The “Carl Zeiss / Jena / No 23175” inscription on the tube is in block letters (not cursive), and of the form that the firm used before introducing its trade mark in 1904. It was probably purchased in the 1890s for use in the Hygienic Laboratory of the United States Marine Hospital Service, a facility that was then located on Capitol Hill in Washington, D.C., and that later became the National Institutes of Health.
- The first Marine Hospital Service Hygienic Laboratory had been established on Staten Island in 1887 by Joseph Kinyoun (1860-1919), a young American physician who had studied bacteriology with Robert Koch in Germany. Kinyoun equipped the Hygienic Laboratory with scientific apparatus “modeled after those used in the laboratory of Dr. Koch,” including “Zeiss’s latest improved microscope objectives and micro-photographic apparatus.” In September 1887, Kinyoun used a Zeiss microscope to examine the “excreta” of sick passengers on an Italian ship recently arrived in New York, and determined that the cause was cholera. This, says historian Eva Ahrén, “was the first time cholera was identified by means of microbial investigation in the Americas.”
