Germanium

In 1886, German chemist, Clement Winkler discovered the element germanium. He had a background in managing a cobalt glassworks and then on the faculty of the Freiberg School of Mining, when he discovered germanium in the mineral argyrodite. Analyzing the silver sulphide ore, he found that all the known elements it contained amounted to only 93 per cent of its weight. Tracking down the remaining 7 per cent, he found the new element he called germanium (for Germany). This turned out to be the eka-silicon predicted by Dmitry I. Mendeleyev in 1871.
