Max Thomas Edelmann

Max Thomas Edelmann (born October 18, 1845 in Ingolstadt , † April 28, 1913 in Munich ) was a German engineer, physicist, university professor and factory owner.

Life

Education and academic background

Max Thomas Edelmann was the son of the high school professor and drawing teacher Leonhard Edelmann. After attending the trade school, he first studied at the Augsburg Polytechnic and the Ludwig Maximilians University in Munich . In 1864 he became a member of the Germania Munich . He took part in the German War as an artilleryman. In 1868 Wilhelm von Beetz became assistant at the physical laboratory of the Technical University of Munich . In 1873 he became a private lecturer. In 1880 he was elected a member of the Leopoldina . In 1881 he was awarded a Dr. phil. PhD. In 1893 he was appointed professor. Among other things, he read about magnetic and galvanic measurements , meteorology and astronomy .

Activities outside the university

In 1870 Edelmann founded his physico-mechanical institute in Munich for the production of physical precision apparatus . He has been working for the court theater administration since the early 1870s and initially took a year off from the university in order to be able to take over the position of head of the entire lighting and mechanical engineering of the two royal court theaters. At Linderhof Palace , he implemented the technical equipment for the Venus Grotto . This included a wave machine and the entire lighting technology, which was fed with internal pole dynamo machines operated by steam engines from our own production facility.

In his institute he manufactured complete cable test vehicles for industrial use to equip power plants. For questions of experimental physics he constructed, among other things, projection instruments, photographic apparatus for registering electrical phenomena and new types of measuring instruments for researching geomagnetism . The measuring devices that resulted from his collaboration with Heinrich von Wild were used in geomagnetic observation stations around the world.

For Friedrich Bezold he made precise tuning forks and an adjustable Galton whistle for very high frequencies to research the residual hearing ability of the deaf . His highly sensitive galvanometers for measuring the smallest voltage differences were also used in medical research, as did his electromagnetic devices in ophthalmology .

Memberships

Edelmann was a member of the Polytechnic Association for the Kingdom of Bavaria. In 1889 he became director of the electrotechnical test station. He was a member of the museum advisory board of the Deutsches Museum and, with his expertise and tools from his production, helped in particular to set up the physics department.

Edelmann was a philistine of the Corps Germania, belonged to the first automobile clubs and the Isartalverein and was an extraordinary member of the artist society Allotria .

family

Max Thomas Edelmann was first married to Anna Maria, nee Geiß, who died in Munich in 1872. In his second marriage he married Sofie Erhardt from Schwabing (born November 1, 1852). The common sons of this marriage were Otto Edelmann (1870–1928) - he became a professor and head of department at the Bavarian State Trade Institute in Nuremberg - and Max Edelmann (1874–1940), who also became a professor and took over his father's institute.
