Zeiss Theodolite

Description
Zeiss brought out its first optical theodolite with graduated glass circles, the Th I, in 1924, and they produced the Th II, a one-second instrument of this sort, during the years 1935-1941. This example may be one of the many instruments that American intelligence officers captured from the German geodetic office at the end of World War II. The U. S. National Imagery and Mapping Agency transferred it to the Smithsonian in 2000.
The signature reads "Th II CARL ZEISS JENA Nr. 34390." A brass tag on the box reads "SICKLER KARLSRUCH.I.B.gegenuber der HAUPTPOST." The inscription painted on the box--"No. 45 AMS GEOD DIV"--refers to the Geodetic Division of the U. S. Army Map Service.
