Rudolf Fuess Berlin Steglitz Anemometer
A portable anemometer or air meter, made by well know scientific instruments maker R. Fuess from Berlin Steglitz in 1930’s. The anemometer was used to measure the air speed for aviation and meteorology. The device is made of nickel cover brass and has a nice silvered dial with five small dials on the face of the large dial, each marked 0-9. Extending from the top is an axis about which four black half spheres rotate upon air pressure.. On the side of the dial there is an on-and-off button. Dimensions: the diameter of the dial is 60 mm and total height just 170 mm. The aluminum case is 7 in X 3 in x 3 in. The anemometer is still in functioning state.

Rudolf Fuess founded his precision instrument workshop in Berlin in 1865. They started making anemometers in 1875 and in 1877 they took over the firm Greiner & Geissler and started making thermometers and barometers. In 1891 they moved to the Steglitz district of Berlin, which they added to their logo. His son Paul Fuess took over in 1913, and Rudolf died in 1917. The company prospered during WWI, but suffered during the German economic crises of the 1920s. They didn’t really recover until 1934, and WWII again brought much business to the company. The postwar years were lean times, as facilities were destroyed during the war. Business improved in the 1950s, but they did not survive the transition to electronic meteorological instrumentation. They closed their doors in 1976, and their facilities in Steglitz were demolished.
An anemometer is a device used for measuring wind speed and direction. It is also a common weather station instrument. The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed instrument used in meteorology. The first known description of an anemometer was given by Leon Battista Alberti in 1450.
