Friedrich Gottlob glasses
Friedrich Gottlob Gläser (born January 29, 1749 in Kamsdorf ; † 1804 ) was a German geologist. He made one of the earliest geological maps in his description of the geology of the county of Henneberg from 1775.
His father Johann Gottlob (1721–1802) was the mountain master of the Neustädter Reviers in Großkamsdorf and at the Suhl Mining Authority, his mother Johanna Frederike daughter of the Freiberg mountain council Johann Friedrich Henkel (1679–1744). Glasses studied at the Freiberg Mining Academy and from 1772 was vice miner at the Suhl Mining Authority under his father. In 1773 he became a mining authority assessor and surveyor (active in the districts of the Neustädter Kreis and in Voigtsberg (Oelsnitz) in the Vogtland) and in 1778 a mountain master and head of the mining authority in Eibenstock in the Ore Mountains . After merging the position with that of Johanngeorgenstadt , he was again in the mining authority of the Neustädter Kreis from 1793. He was probably also the official successor of his father in the Suhl Mining Authority in 1801.
In his map of the Henneberg area from 1771, he distinguished between sand mountains (red sandstone), limestone mountains (shell limestone) and granite (including other igneous rocks such as porphyry). He was one of the first to differentiate formations in a geological map by color, following a suggestion by Georg Christian Füchsel , from whom the first geological map in Germany (1762) comes. In his book he also covers the history of mining in Hainaut.
He was an honorary member of the Leipzig Economic Society and from 1777 a member of the Academy of Non-Profit Science in Erfurt .
