Description
This is a compound monocular designed for petrographic work. It has coarse and fine focus, analyzer in the tube, large circular mechanical stage, inclination joint, sub-stage polarizer, sub-stage mirror, horseshoe base, and wooden box. The inscription on the base reads “R. FUESS / STEGLITZ-BERLIN / 1380.” The serial number indicates a date of around 1907.
Rudolph Fuess (1838-1917) began as an instrument maker in Berlin in 1859, acquired the workshop of Greiner & Geissler in 1876, and began making petrographic microscopes around that time. The firm moved to Steglitz, a suburb of Berlin, in 1891.
This was owned and used by Charles Whitman Cross (1854-1959), an American geologist who specialized in the classification of igneous rocks, worked for the U.S. Geological Survey, and became an Associate in Petrology at the Smithsonian Institution.
