Hermann Heymann
(ca.1800-1871)

Hermann Heymann was born in Germany, probably to a Jewish family, and established a mineral and fossil dealership in Bonn. He may also have had a shop or a distributor in France, as the printed portion of one Heymann label is in French ("Hermann Heymann à Bonn. Comptoir minéralogique et paléontologique."). One handwritten label in the archive is marked "Heymann 1863." A published notice in 1860 for the "Mineralien-Handlung von Hermann Heymann, Grubenverwalter [mine manager]" states his address as being on Poppelsdorfer Allee in the neighborhood of the Natural History Museum. He was also a "Mine Director" in Bonn, though this may simply have been one of those German civilian rankings that they were so fond of bestowing. Nevertheless, in 1867 he reported on the levels of groundwater in the city of Bonn near the Rhein, so he seems to have been employed in some geological capacity.

Heymann had a fine collection of meteorites which was the subject of a study by Spiridon Simonowitsch. It appears, from a label in the Museum of Victoria, Australia (shown here), that he also had a personal collection of minerals which he sold to the Bonn mineral dealer Dr. August Krantz (source of the Museum's specimen) around 1860. The label is marked "Min. Sammlung von H. H. in B."

In 1871, the year of Hermann Heymann's death, another Hermann Heymann (born Feb. 1852; probably his son) and his wife Caroline emmigrated to the United States and settled in New York City. They had two daughters: Jennie (1877) and Bertha (1885), both of whom are listed in the 1900 census for Manhattan as "sales lady," perhaps in the employ of their father (who is listed simply as a "collector"). Caroline and Hermann also appear on the 1910 census, again as a "collector."

A David Heymann, son of Hermann Heymann and wife Gertrud (nee Davids) was born in Bonn in 1851 and worked as a "stone polisher" and later a coal dealer. He died in 1929 and was buried in the Jewish Cemetery in Noerdlingen, Bavaria. Incidentally, the first person buried in the Jewish Cemetery in Bonn (in 1873)was an infant named Hermann Heymann.
