Otto Bohne Barometers
These are four aneroid barometers from the collection of Josef Lang of Germany, made by the firm Otto Bohne. After working in Paris, possibly for Naudet (PHBN), Bohne founded his own factory in Berlin in 1863. His barometers were copies of PHBN barometers, possibly under license since they have the label 'holosteric' (non liquid) which is typical of PHBN barometers. He invented methods of making aneroid barometers temperature compensated.
Early barometers were made for use by scientists. Later Bohne produced barometers for the public. The firm made barometers used in upper air balloon flights in Berlin in the 1890s, and altimeters used in aviation in World War I. The firm exhibited its instruments in Berlin in 1979, in Chicago in 1893, and in Berlin in 1899.
His successors in 1906 were Louis Kurth and Otto Kohlman, who called their firm Otto Bohne Nachfolger (successor). They exhibited in Brussels in 1910. A 1912 Otto Bohne Nachfolger catalog is available on this website. The last we know of this firm was circa 1927.
