History
Germanium disulfide was the first germanium compound found by Clemens Winkler, during the analysis of argyrodite. The fact that germanium sulfide does not dissolve in aqueous acid made it possible for Winkler to isolate the new element.
Production
Germanium disulfide is created by passing hydrogen sulfide with germanium chloride in a concentrated hydrochloric acid solution.
