"He was born at Berlin in 1810, and early received encouragement from King Frederick William III. He entered the academy in 1826, and worked under Professor Buchhorn. Inconsequence of the success of his first work,´ The Warrior and his Daughter,´ after Hildebrand, in 1830, he was appointed by the academy to engrave the ´Loreley´ after Regass. In the same year he obtained a third class medal at Paris, and in 1844 a second class. In 1855 he sent to the Paris Universal Exhibition, ´Christ weeping over Jerusalem,´ after Ary Schefier, the ´Portrait of Frederick William TV. after Otto; ´Two Children,´ after Magnus, and his famous ´Portrait of Charles I,´ after Vandyke; and was rewarded with a medal of the first class. He was appointed professor of engraving in 1842." - (en.wikipedia.org 30.10.2019)
