Christian August Hermann Marbach (born April 11, 1817 in Jauer , Jauer district , province of Silesia , † April 25, 1873 in Breslau ) was a German physicist, mineralogist and crystallographer.

Life

Christian August Hermann Marbach studied at the University of Breslau and was awarded a doctorate on March 30, 1844. phil. PhD . He then became a teacher and later a senior teacher and prorector at the Breslau secondary school " Zum Heiligen Geist ".

On February 6, 1858, Christian August Hermann Marbach with the academic surname Frésnel was accepted as a member ( matriculation no. 1853 ) in the Leopoldina Scholars' Academy .
