Adolf Mosengel spent years studying with very well established artists.
From 1854 to 1857, Mosengel studied at the Kunstakademie Dusseldorf under Hans Gude, and from 1858 to 1859 in Paris. Hans Fredrik Gude (March 13, 1825  August 17, 1903) was a Norwegian romanticist painter and is considered along with Johan Christian Dahl to be one of Norway's foremost landscape painters. He has been called a mainstay of Norwegian National Romanticism. In 1861, he studied in Geneva with Alexandre Calame, before settling in Hamburg, where he joined the Hamburg Artists' Association. Alexandre Calame (28 May 1810  19 March 1864) was a Swiss landscape painter, associated with the Dusseldorf School. He became quite well known, especially in Germany, although Calame was more a drawer than an illustrator.
