Vintage R. Fuess Berlin-Steglitz Scientific Instrument - Spectroscopy Apparatus For Sale

R. Fuess Berlin-Steglitz Nr. C7837 Scientific Instrument - Spectroscope?this listing includes this inoperative and dysfunctional R. Fuess Berlin-Steglitz Nr. C7837 Scientific Instrument .. selling as parts source or to add to a possible collection of instruments.. the power cord is frayed beyond use, and also dirt and corrosion within the chassis..there are some highly valuble components manufactured by HYDRA WERK on the chassis! that could be harvested.. it looks to be some sort of spectroscope but probably works or operates in coordination with other instrumets since there are jacks/plugs in the backside and the power cable with a 2 prong plug (250V 50hZ) would plug into a power supply of some sort..translating from German to English \"Bogenanreger\" = ARC EXCITATION
\"Widerstand\" = RESISTANCE
\"Probentisch\" = SAMPLE TABLE
\"Netzschalter\" = POWER SWITCH
\"Zusatzkapazität\" = ADDITIONAL CAPACITY Biography:Rudolf Fuess was born on September 28, 1838 in Moringen. He was apprenticed as a mechanic after completing school to Hermann Pfaff in Gottingen and Hugo Schroder in Hamburg. Fuess began to do special order work in 1859 in Berlin. In 1865 he opened an independent workshop at Mauerstrasse 84. In 1870 the workshop moved to Wassertorstrasse 46.In 1871 Paul Heinrich Groth (1843-1927), \"the father of modern crystallography,\" and an instructor of mineralogy at the University of Berlin, commissioned Fuess to make him a \"crystal-optic universal apparatus.\" He said, \"In Mr. Fuess I was fortunate to find an artist who was not only able to build the apparatus but also simplify and improve individual components thereof.\"The Fuess company became famous for its goniometers. Fuess developed his most important goniometers between 1873 and 1879. At the Berlin Industrial Exhibition of 1879, he exhibited his Models I and II, as well as his microscope- and lever-arm goniometers.In the 1870s, the company was also was well known for making petrographic thin sections, of which the most comprehensive sets contained a thousand rock types. Fuess also marketed stone saws and cutting machines to institutes, so that they could make their own thin sections.The company moved to larger quarters at Jakobstrasse 108, where Fuess employed five mechanics, two opticians, and two apprentices.In 1875-1876, Fuess collaborated with Professor Harry Rosenbusch (1836-1914) in making the first completely equipped polarizing microscope. After this, polarizing microscopes became another mainstay of the R. Fuess workshop, culminating in the construction of a theodolite microscope after Evgraf Fedorov (1853-1919) in 1929.After the purchase of the glass manufactory, Greiner & Geissler in 1877, the Fuess company built more meteorological, geodetic, and hydrographic instruments, as well as spectrometers and heliostats.Fuess was a central figure in his workshop, being manager, designer, draftsman and works director, all in one person. In 1913, Fuess transferred the company to his son Paul. He died in Steglitz in 1917.Established in Berlin in 1865, the firm of Rudolf Fuess quickly rose to prominence as an optical instrument maker. Five years after it was started, it needed to move to larger quarters, and in 1892, the firm relocated its headquarters to a Berlin suburb, Steglitz, in order to have room for further expansion.Rudolf Fuess (1838-1917) was the key player in his workshop, being both manager, director, designer, and engineer all in one. For the early history of the company, see the constituent record for Rudolf Fuess.In 1913, Fuess transferred the business to his son Paul. In 1932, the company opened an American office in New York City under the name of R. Fuess, Inc. In 1936, another branch was opened in Potsdam. This branch principally made aviation instruments.In the 1930s, the Fuess company was famous for precision instruments in seven departments:1) instruments to measure air pressure, temperature, and humidity; testing apparatus; open air housings.2) instruments to measure wind, rainfall, evaporation, radiation, and sight.3) thermo-control instruments for the measurement of flow, pressure, and vacuum.4) microscopes and instruments for general optical observation and material research.5) spectroscopic apparatus, goniometers, refractometers, and crystallo-optical apparatus.6) apparatus for measuring water levels and quantities.7) apparatus made to order.At the height of its operations, the R. Fuess company had 3000 employees. Work came to a standstill, however, with the defeat of Germany in World War II and the partition of the country. Production resumed in 1948 or 1949. Although the firm was able to mark its 100th anniversary, its product--precision mechanical-optical apparatus--could not compete with the newer electronic optical apparatus. The firm was dissoved in 1976, and the factory demolished the same year.selling as a possible candidate for an exclusive German scientific instrument collection, in inoperative and incomplete condition. you will drive your wheels off trying to find this same item  elsewhere..
