Live and act

Universal instrument according to Tesdorpf

Ludwig Tesdorpf came from the Lübeck Tesdorpf family . His father was the businessman Hermann Matthäus Tesdorpf (1833–1868), his mother Emilie Luise, b. Oppenheimer (1835-1919), who later worked as a writer. He came to Germany when he was ten. From 1866 to 1868 he attended the Salzmann Institute in Schnepfenthal and from 1868 to 1872 the secondary school in Jena . At Carl Zeiß in Jena he learned the craft of precision mechanics, where he was trained personally by Carl Zeiß.

Tesdorpf worked from 1876 to 1879 as an assistant in the workshops of Max Hildebrand in Freiberg and Carl Bamberg in Berlin . Then he attended the Technical University of Karlsruhe . After completing his studies, he became managing director of the Mathematical-Mechanical Institute Gebr. Zimmer in Stuttgart. In 1882 he took over the company.

Here he mainly manufactured geodetic surveying instruments such as the universal instrument, but also other scientific instruments and apparatus. At considerable expense he developed geomagnetic instruments that were tested by the German South Pole Expedition and the Norwegian Northern Lights Expedition. Tesdorpf worked with well-known scholars of his time such as Max Eschenhagen and Friedrich Bidlingmaier in Berlin, Prof. Schmidt and Prof. Haußmann in Aachen and Prof. Schmidt in Stuttgart. At the suggestion of August Schmidt, professor of mathematics and physics at the Dillmann Realgymnasium in Stuttgart and from 1896 to 1912 head of the meteorological-geophysical department of the State Statistical Office in Stuttgart, seismometric devices were produced, in particular the Schmidt trifilar gravimeter . Tesdorpf developed precise material testing equipment under the suggestion and cooperation of building director Carl von Bach .

In 1898 he had a large workshop building built in the Stuttgarter Forststraße, which contained 600 square meters of work space and in which 30 to 36 workers were employed. Tesdorpf gained a worldwide customer base through the precision and beauty of its instruments. Tesdorpf's instruments won prizes at all exhibitions. In 1903 he was awarded the gold medal for art and science by the King of Württemberg.

For many years he was chairman of Section IX of the trade association for precision mechanics and a board member of the German Society for Mechanics and Optics. In 1900 he organized the 11th German Mechanics' Day in Stuttgart in 1900. He has been a member of the school council since the foundation of the technical college for precision mechanics in Schwenningen in 1900.

He was first with Dorette, geb. Haas married; after her death in 1887 with Elisabeth, b. Stettner; from both marriages he had two sons and four daughters.

After his death, the workshop was taken over by the Göttingen company Sartorius in 1906 .
