Description

A mass of brown, crystalline bustamite, arranged in parallel-grown aggregates with little luster.

Comes with antique label dated 19th century. Louis Sæmann was born in Görlitz, Saxony, on November 11, 1821. He began as a fossil collector and worked for Adam August Krantz (1808-1872) in Berlin before opening his own competing shop in Paris in 1850. He was apparently well versed in the science of mineralogy, and wroter of various paleontological studies as well. He died in Paris, France on September 13, 1866, and his mineral business was then purchased by his old mentor, Adam Krantz in Bonn.
Several important Saemann specimens are preserved today in the School of Mines, Paris. The Australian Museum in Sydney acquired 536 mineral specimens from Sæmann in 1861.
