Hideyo Noguchi (1876-1928) was a Japanese bacteriologist who moved to the U.S. in 1900 to work with Simon Flexner at the University of Pennsylvania. A few years later, having gone with Dr. Flexner to the newly-established Rockefeller Institute for Medical Research in New York, Dr. Noguchi used this microscope to study of the causal agent of syphilis.
This is a compound monocular with coarse and fine focus, triple nosepiece, large circular stage covered with vulcanite, trunnion, Abbé illuminating apparatus, black horseshoe base, and wooden box with extra lenses. The “CARL ZEISS / JENA” logo, introduced in 1904, appears on the tube. The serial number is 51900.
