How did Clemens Winkler Discover germanium?
Germanium was discovered by Clemens A. Winkler in 1886, in Germany, in a mineral sample from a silver mine. Analysis indicated the sample – a rather rare mineral called argyrodite – contained 73 – 75% silver, 17 – 18% sulfur, 0.2% mercury, and 6 – 7% a new element, which Winkler named germanium.
