"Andreas Achenbach (29 September 1815, Kassel – 1 April 1910, Düsseldorf) 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." - (en.wikipedia.org 15.02.2022)
