Translated from German wikipedia:
Wilhelm Steuerwaldt was born in today’s house Finkenherd 1 in Quedlinburg as the son of a drawing teacher and had close contact with painting even in his youth. After attending school, he studied at the Düsseldorf Art Academy from 1833. Before that, he had been an apprentice to the Halberstadt architectural painter Carl Hasenpflug from 1830 to 1833. In 1836 he returned to Quedlinburg, where he worked as a drawing teacher and painter until the end of his life, creating over 200 paintings, mainly with romantic motifs from his hometown, but also from some places in the Harz Mountains. In 1839 he acquired the Klopstockhaus in Quedlinburg, which he owned until shortly before his death and sold in 1867.
