Andreas Achenbach was a German landscape and seascape painter in the Romantic style. He is considered to be one of the founders of the Düsseldorf School.[citation needed] His brother, Oswald, was also a well known landscape painter. Together, based on their initials, they were known as the "Alpha and Omega" of landscape painters.
Oswald Achenbach was a German painter associated with the Düsseldorf school of painting. Though little known today, during his lifetime he was counted among the most important landscape painters of Europe. Through his teaching activities, he influenced the Kunstakademie Düsseldorf. His brother, Andreas Achenbach, who was twelve years older, was also among the most important German landscape painters of the 19th century. The two brothers were humorously called "the A and O of Landscapes" (a reference to their initials matching a common German reference to the Alpha and Omega).
