Weimar Saxon-Grand Ducal Art School
Carl Arp (born 3 January 1867 in Kiel, died 6 January 1913 in Weimar) was a German landscape painter. He is best known as a founding member of the Schleswig-Holsteinische Kunstgenossenschaft and representative of the Weimar Saxon-Grand Ducal Art School (Grossherzoglich-Sächsische Kunstschule Weimar). Subsequent to his studies there under Theodor Hagen and Leopold von Kalckreuth, he spent several years in Italy. Carl Arp is viewed as one of the main representatives of the "en plein air" style of landscape painting.
