Johann Friedrich Ludwig Hausmann

Johann Friedrich Ludwig Hausmann (22 February 1782 – 26 December 1859) was a German mineralogist.

Two years after making a geological tour of Denmark, Norway and Sweden in 1807, he was placed at the head of a government mining establishment in Westphalia, and established a school of mines at Clausthal in the Harz mountains.

[1] In 1811 he was appointed professor of technology and mining, and later of geology and mineralogy at the university of Göttingen, which he occupied until shortly before his death.

[1] He published observations on the geology and mineralogy of Spain and Italy as well as that of central and northern Europe: he wrote on gypsum, pyrites, felspar, tachylite, cordierite and some eruptive rocks, and devoted much attention to the crystals developed during metallurgical processes[2] In 1816, with Friedrich Stromeyer, he described the mineral allophane.

[3] In 1847 he coined the mineral name biotite in honor of physicist Jean Baptiste Biot.
