Fireside Chat “Antique mineralogical instruments – the Medenbach collection”

October 14, 2023 @ 5:00 pm - 6:00 pm BST

Presented by Olaf Medenbach.

Synopsis

3 petrographic microscopes by Nachet & Fils, Paris, ca. 1920, ca. 1880 and 1914 (from left).

Mineralogy is a classical natural science and deals with the physical and chemical properties of minerals and synthetic crystals and materials. Though it might be defined as a branch of solid-state physics, the scientific instruments used in mineralogical basic research and routine work are peculiar – most of them were especially designed for mineralogical use and exclusively applied in this field.

Two-circle goniometer after Goldschmidt made by Stoe in Heidelberg/Germany, ca. 1895.

The Medenbach collection of antique mineralogical instruments was accumulated over a period of more than 30 years. It comprises more than 450 instruments and accessories ranging from the first contact goniometers from the 18th century to the highly sophisticated theodolite-microscopes of the early 20th century.
