Friedrich Mohs (1773-1839) German
geologist/mineralogist.Mohs, studied chemistry,
mathematics and physics. He started classifying
minerals by their physical characteristics, in
spite of their chemical composition, as it was
done before. He created a hardness scale that is
still used as Mohs scale of mineral hardness.
