This is an example of the Zeiss small compound monocular model VIb. It has coarse and fine focus, double nosepiece, circular stage, sub-stage diaphragm, sub-stage mirror, horseshoe base, and wooden box with extra lenses. The inscriptions read “CARL ZEISS / JENA” and “GERMANY.” The “62195” serial number indicates a date of around 1913. Another inscription reads “Neuro Lab, H.P.F.G.” A brass plate in the box reads “IMPORTED BY / ARTHUR H. THOMAS CO. PHILADELPHIA.” There are two Zeiss objectives, and two cases for Leitz objectives.
This was used by Adolf Meyer (1866-1950), the Swiss-born physician who joined the Henry Phipps Psychiatric Clinic at the Johns Hopkins School of Medicine in 1913, served as psychiatrist-in-chief at the hospital until 1941, and played a major role in establishing psychiatry as a clinical science.
