Johannes Bartholomäus Duntze was a German landscape painter
He was born in Rablinghausen near Bremen south of Düsseldorf on 6th May 1823 and died just over 72 years later on 20th May 1895 at Düsseldorf. He enjoyed an extensive training, beginning in 1838 at the Munich Akademie. He then went to Berlin to study under Professor Krause and from there travelled to Antwerp. During 1851-55 he lived in Geneva where he furthered his knowledge in the studio of Alexandre Calame (1810-64).

The latter, who delighted in painting mountainous views, had also studied the Dutch masters such as Hobbema, Ruysdaël and Paul Potter, all of whose work appears to have influenced Duntze's own style. After Geneva there followed a short stay in Paris until 1856 when Duntze returned to Düsseldorf. Apart from his numerous painting expeditions, he remained in Düsseldorf for the rest of his life.
