Georgius Agricola was a German Renaissance 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 was the first to drop the Arabic definite article al-, exclusively writing chymia and chymista in describing activity that we today would characterize as chemical or alchemical, giving chemistry its modern name. For his groundbreaking work De Natura Fossilium published in 1546, he is generally referred to as the father of mineralogy and the founder of geology as a scientific discipline. April 2, 1494 – December 1, 1555; died at 61. Alive at the same time as Michelangelo, Martin Luther, Christopher Columbus, Niccolò Machiavelli, and Michel de Montaigne. Wiki link
