Friedrich Mohs
German geologist and mineralogist (–)
For the American dermatologist, see Frederic E. Mohs.
Carl Friedrich Christian Mohs (MOHZ, German:[ˈfʁiːdʁɪçˈmoːs]; 29 January – 29 September ) was a German chemist and mineralogist. He was the creator of the Mohs scale of mineral hardness. Mohs also introduced a classification of the crystal forms in crystal systems independently of Christian Samuel Weiss.
Early life and education
[edit]Mohs was born on 29 January , in Gernrode, in the Harz mountains, Anhalt-Bernburg (present-day Saxony-Anhalt, Germany). He showed an interest in science at an early age and received private education before entering the University of Halle.[4] There, Mohs studied chemistry, mathematics and physics. In , he joined the Mining Academy in Freiberg, Saxony, being a lärjunge of Abraham Gottlob Werner.
Career
[edit]After acquiring the job of a foreman at a mine in , Mohs relocated in to Austria, where he was employed in

mineralogy, geology.
One of Abraham Werner’s outstanding students, Mohs made his primary scientific contribution in systematic mineralogy. He also proposed the scale of hardness for minerals, which is named for him and which is still in use.
Mohs displayed a marked interest in science at an early age and received a private education before entering the University of Halle in In he matriculated at the mining academy at Freiberg, where in addition to physics and mathematics he studied mineralogy under Werner. In Mohs was invited to Great Britain by his fellow students George Mitchell and Robert Jameson to participate in the planning of a mining academy at Dublin. Although the proposed academy was never established, the journey enabled Mohs to study the geology and mineralogy of Ireland and Scotland and to make lasting friends among Scottish geologists.

Job and Career
[change | change source]Scientist Mohs was born in Germany. He was a minerologist who studied minerals, chemistry, physics, and mathematics.
He moved to Austria in where he found a job identifying minerals in a collection that belonged to a rich banker. He used physical characteristics of the crystals to determine what they were. One of the characteristics he used to identify minerals was their hardness.
He knew that some of the minerals could scratch others and that if a mineral could make a scratch on another, it must be harder than the mineral that was scratched. He found that all minerals could scratch the mineral talc, so it must be very soft. He also found that diamonds were so hard that no other minerals could scratch them.
In , Mohs made a scale from 1 to 10 to describe mineral hardness. He gave harder minerals larger numbers and softer minerals smaller numb
