Oswald Achenbach (February 2, 1827 - February 1, 1905) was a German landscape painter.
Born in DÃ¼sseldorf, he received his art education from his brother, Andreas Achenbach. His landscapes generally dwell on the rich and glowing effects of color which drew him to the Bay of Naples and the neighborhood of Rome. He died in DÃ¼sseldorf. He is represented at most of the important German galleries of modern art.
