Georgius Agricola was a German Humanist scholar, mineralogist and metallurgist. Born in the small town of Glauchau, in the Electorate of Saxony of the Holy Roman Empire, he was broadly educated, but took a particular interest in the mining and refining of metals. He is well known for his pioneering work De re metallica libri XII, that was published in 1556, one year after his death.
