Germanium was predicted as a hypothetical 'ekasilicon' in 1869 by Russian chemist Dmitri Mendeleev when he noticed a gap between silicon and tin on the periodic table. It was truly discovered in Germany in 1889 by Clemins Winkler; after examining a mineral sample from a silver mine. He  named the new element Germanium after the Latin 'Germania' meaning Germany.

Pure germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature.

The largest use of germanium is in the semiconductor industry. When doped with small amounts of arsenic, gallium, indium, antimony or phosphorus, germanium is used to make transistors for use in electronic devices. Germanium is also used to create alloys and as a phosphor in fluorescent lamps. Both germanium and germanium oxide (GeO) are transparent to infrared radiation and are used in infrared optical instruments and infrared detectors. Some germanium compounds seem to be effective in killing some types of bacteria and are currently being studied for use in chemotherapy.

Germanium is a very important element for our lives today. Germanium is used in transistors; transistors are used in most computers to store memory, cameras, and there are over 2 million transistors used in the iPhone. Germanium is also used in most radios and hearing aids, not to mention the use of it in fluorescent lights.

Germanium can found as a by-product of mining and processing zinc and copper. Though scarce, it is not rare. It can be found in minerals but only in trace amounts. It is a solid at room temperature.
