Joseph Ruep (April 10, 1886-1940) was a German landscape painter active in the late 19th and early 20th centuries. Ruep was born in Isny and studied art in Kemptan, Bavaria. After his studies, Ruep returned to Isny where he took work with a postcard company. Striking out on his own in 1915, Ruep relocated to Munich where he helped to develop a new style of topographical and relief drawing. He also became known as a master view maker and was frequently contracted to paint bird's-eye perspective views of estates, resorts, cities, and important buildings. Ruep died in Bad Hindelang, Bavaria, Germany.
