Germanium is created by stellar nucleosynthesis, mostly by the s-process in asymptotic giant branch stars. The s-process is a slow neutron capture of lighter elements inside pulsating red giant stars. [57] Germanium has been detected in some of the most distant stars [58] and in the atmosphere of Jupiter. [59]
The first organogermanium compound, tetraethylgermane, synthesized by Winkler in 1887, [3] by the reaction of germanium tetrachloride with diethylzinc. More commonly, these Ge(IV) compounds are prepared by alkylation of germanium halides by organolithium and Grignard reagents , including surfaces terminated with Ge-Cl bonds. [ 4 ]

The discoveries of the 118 chemical elements known to exist as of 2025 are presented here in chronological order. The elements are listed generally in the order in which each was first defined as the pure element, as the exact date of discovery of most elements cannot be accurately determined.
For example, this is why the template writes "(at 0 °C)". For this, you may want to experiment with parameter input too - or propose improvements. All this can vary across the values (data rows). So depending on the row and the specific value, additional formattings may be added by the template (e.g., a newline <br/>) Central data values
1912 – Stainless steel invented by Harry Brearley; 1916 – Method for growing single crystals of metals invented by Jan Czochralski; 1919 – The merchant ship Fullagar has the first all welded hull. 1924 – Pyrex invented by scientists at Corning Incorporated, a glass with a very low coefficient of thermal expansion
