Arnold Constantin Peter Franz von Lasaulx (14 June 1839 – 25 January 1886) was a German
mineralogist and
petrographer.
Life
He was born at
Kastellaun near
Coblenz, and educated at the
University of Berlin, where he took his Ph.D. in 1868. In 1875, he became an associate professor of mineralogy at
Breslau,[1] and in 1880, a professor of mineralogy and
geology at
Bonn. He was distinguished for his researches on
minerals and on
crystallography, and he was one of the earlier workers on microscopic
petrography. He described in 1878 the eruptive rocks of the district of
Saar and
Moselle.[2]
In 1880 he edited "Der Aetna" from the manuscripts of
Wolfgang Sartorius von Waltershausen, the results of observation made between the years 1834 and 1869. He was author of "Elemente der Petrographie" (1875), "Einführung in die Gesteinslehre" (1885), and "Précis de petrographie" (1887). He died at Bonn in January 1886.[2]
