from Wikipedia, the free encyclopedia

Johann Friedrich Carl Klein (born September 15, 1842 in Hanau ; † June 23, 1907 in Berlin -Charlottenburg) was a German mineralogist and crystallographer .

Life

Klein studied natural sciences in Berlin, Tübingen and Heidelberg. He received his doctorate from Heidelberg University in 1868 (Dr. phil.). In July 1869 the habilitation followed. Klein was a private lecturer in Heidelberg, from 1873 associate professor and from 1877 professor of mineralogy at the University of Göttingen and director of the Mineralogical-Petrographic Institute. There he headed the Mineralogical-Petrographic Institute and the associated collection. Among other things, Friedrich Rinne was his assistant there. In 1887 Klein went to the Humboldt University in Berlin as Professor of Geology and Director of the Mineralogical-Petrographic Institute and the associated collection. Secret mountain ridge was small.

He introduced new polarization microscopic techniques to study minerals and studied their optical properties. Another research focus was meteorites . He expanded the collection of the Natural History Museum in Berlin from 217 to 500 copies.

Honors and memberships

In 1882 Klein was elected a member of the Leopoldina . In 1877 he was elected a full member of the Göttingen Academy of Sciences . In 1887 he became a member of the Berlin Academy of Sciences and the Heidelberg Academy of Sciences and in 1895 he became an honorary member of the Mineralogical Society of Great Britain and Ireland . In 1900 he was accepted as a corresponding member of the Académie des Sciences in Paris.

A new mineral described by A. Sachs in 1905 was named Kleinite in his honor .
