Minerals cabinet

Waldin, who also gave lectures on mineralogy , got access to the mineral and rock collection of the geologist Nathanael Gottfried Leske , which was also known as the Museum Leskeanum , when he was appointed professor of finance and economics at the University of Marburg in 1786 . Leske sent his collection in advance, but had an accident on his journey with his carriage and died shortly afterwards. Waldin suggested the Landgrave Wilhelm IX. proposed to purchase the collection in order to build a Hessian mineral collection. However, the landgrave refused to buy it because the price of 6,000 Reichstalers seemed too high to him. Waldin then suggested that responsible miners should be instructed to send ore stages , rock samples and fossils from all Hessian mines to the University of Marburg. The Landgrave accepted this suggestion and on July 29, 1790, entrusted him with the supervision of the Hessian Minerals Cabinet . Shortly afterwards he received large quantities of rock samples, minerals and fossils that came from the mines and smelters in Frankenberg , Homburg and others; since then, the collection has also appeared as a mineralogical museum . In 1791 the Landgrave assigned him as inspector the public supervision of the collection, which was in the university under the library. After his death, the cabinet was continued by Johann Christoph Ullmann .

Trivia

The mineralogical museum of the Philipps University of Marburg is located today in the granary and bakery of the Teutonic Order built in 1515 on Firmaneiplatz. The collection currently comprises, in two superimposed halls with a total area of ​​600 square meters in 51 wall and display cases, around 60,000 minerals, around 55,000 rock samples, 15,000 raw gemstone samples and 150 meteorites, of which around 3,000 are exhibits. This inventory makes it the largest mineralogical collection in Hesse and also establishes its reputation as one of the most important specialist museums in Germany.
