biography

His grandfather was Johann Valentin Meidinger . His parents were the Niederrad pastor Johannes Meidinger (1799–1843) and Antionette (1807–1844), a daughter of the Dutch captain Ludwig Buff.

From 1849 he studied natural sciences in Giessen under the direction of his uncle Heinrich Buff . During his studies he became a member of the Cattia Gießen fraternity in the winter semester of 1849/50 . After receiving his doctorate in 1853, he made further studies in Heidelberg, Paris and London. After his habilitation in 1857, he was a private lecturer in technology in Heidelberg. He was a member of the Society of German Natural Scientists and Doctors .

Around 1853 he dealt with voltametric measurements . In 1859 he invented a galvanic voltage source, the Meidinger element , which delivered a constant voltage, as required by the communications media in telegraph and rail traffic. As an improvement on the Daniell element , it has a storage vessel with copper sulfate crystals, which ensure that the concentration of the copper sulfate solution is maintained.

In 1864/65 he became chairman of the newly founded Grand Ducal State Trade Hall in Karlsruhe at the Baden Ministry of Commerce. Their task was to disseminate knowledge about advances in science and technology through exhibitions and publications in the Badische Gewerbezeitung , of which he was editor from 1867.

In 1869 he became professor of technical physics at the Technical University in Karlsruhe. He was also secretary of the Natural Science Association in Karlsruhe. After his death, a street in Karlsruhe was named after him.

Meidinger furnace

He worked in many areas of technology: electroplating, electrical power machines, firing, heating and lighting, factory hygiene and housing, and in 1869 he constructed the first slow-burning furnace . This turned out to be very practical for the time and was also used outside of Germany. In 1872, in cooperation with the Viennese entrepreneur Hermann Heim, a Meidinger furnace factory was founded, which was exclusively authorized by Meidinger.

Around 1870 he designed a simple ice cream machine for domestic use based on the principle of the cold mixture. In the harsh winter of 1870/71 he built a drying tower for the Lazareth laundry in Grünwinkel . The Meidinger washer is a cover over chimney mouths and is intended to improve draft.
