Johann Wilhelm Gottlob Buzengeiger
Johann Wilhelm Gottlob Buzengeiger (born June 25, 1778 in Tübingen ; † October 26, 1836 there ) was a university mechanic, optician and watchmaker in Tübingen. He was a brother of the mathematician and mineralogist Carl Buzengeiger .
Live and act
Johann Wilhelm G. Buzengeiger was employed as a university mechanic at the University of Tübingen from 1805 to 1836 . He mainly worked for the astronomer and mathematician Johann Gottlieb Friedrich Bohnenberger , but also had a watchmaker's workshop in Tübingen. He also sold his instruments internationally outside the state borders of the Kingdom of Württemberg , e.g. B. to Heinrich Christian Schumacher in Altona . He had health problems from dealing with mercury regularly .
For the national survey planned by Bohnenberger , in 1818 he made replicas of the Toise du Pérou and a heliostat based on a design by Carl Friedrich Gauß , a gyroscope as an astronomical demonstration object (1817), a reversing pendulum for the precise calculation of the force of gravity (1811) and an electroscope invented by Bohnenberger to determine the electrical charge. He also made barometers , Zambonisäule , z. B. as the energy source of a clock, astronomical pendulum and third clocks and a precision balance for the chemist Christian Gottlob Gmelin .
Correspondence
Johann Friedrich Benzenberg
The Düsseldorf astronomer Johann Friedrich Benzenberg wrote the following about Buzengeiger in December 1810:
“B [ohnenberger] showed me a kind of swing machine, which explains the retreat of the night equals [...] in a vivid way, and at the same time shows the physical reason for it. A small earth made of wood and filled with lead turns around its axis, and is set in a rotating motion by the winding of a cord, like the curl with which the boys play. The poles are fixed in a ring, which has a compass suspension and can rotate freely in all directions. If one now lets the earth rotate, one can walk around with it in the whole room without changing the direction of its axis of rotation. "
In another letter dated December 1810, he wrote:
"I ordered a BOHNENBERGER swing machine from the local watchmaker BUZENGEIGER, which he delivers very neatly for a small price of 12 guilders ."
Eduard Mörike
Eduard Mörike wrote 1,836 letters to Buzengeiger and K. to the optician Öchslen, F. Trostel before 20 June, W. G. B. Baumann, where he was one of these to the production magic lantern asked for his idea and probably papercut illustrations from the Telegraph for Germany added . The opticians contacted either refused to accept an order or asked too much, so that he did not discuss the planned project again with the sheet metal manufacturer Karl Deffner until May 9, 1847 through his brother.
