Notes / Further information

During foundation work at the St. Nikolai church in Hamburg, Germany, numerous crystals were found in a brownish-black layer of peat-soil in 1846.
The crystals were examined, described and named in honor of Minister von Struve by the chemist/pharmacist Georg Ludwig Ulex (Hamburg, 1811-1883).
Heinrich Christoph Gottfried von Struve (1772-1851) was "kaiserlich-russischer Geheimer Rat, außerordentlicher Gesandter und bevollmächtigter Minister bei den freien und Hansestädten" as well as founder of the Natural History Museum of Hamburg.
