History

Germanium sulfide was the first germanium compound found by Clemens Winkler during the analysis of argyrodite.The fact that germanium sulfide is not soluble in acidic water made it possible for Winkler to isolate the new element from the other elements.cite journal | author = Clemens Winkler | title = Mittheilungen über das Germanium | journal = J.
