Winkler discovered Germanium in 1886. Germanium is usually obtained from flue dusts of smelters procession zinc ores. It is
also obtained from from the by-products of combustion of certain coals. It is a very important semiconductor material. When Germanium is mixed with
arsenic, gallium, and other elements, they are very important in transistors for
electronic equipment. Germanium oxide's high index of refraction and dispersion has
made it useful as a component of glasses used in wide-camera lenses.
