Andreas Achenbach (1815-1910) was a German landscape and seascape painter in the Romantic style.
He is considered to be one of the founders of the Düsseldorf School.
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.
Achenbach was one of the founding members of an art association known as "Malkasten" (The Paint Box) and helped them acquire the former estate of the Jacobi family in Pempelfort, which was turned into the "Malkastenpark"; now a National Monument.
He took very few students other than his brother, notably Albert Flamm, Marcus Larson, Apollinary Goravsky and William Stanley Haseltine.
He received many honors throughout his life including the Order of leopold (1848), Order of Saint Stanislaus (1861) and the Order of St. Olav (1878).
He became an honorary member of the Pennsylvania Academy of Fine Arts in 1853 and a member of the Accademia di Belle Arti di Brera in 1862.
In 1885, he was named an honorary citizen of Düsseldorf.
When he died, he was a given a grand viewing and ceremony at the Malkasten house. He was buried in a magnificent tomb with a sculpture by Karl Janssen.
There is a street, the "Achenbachweg" named after him in Holsterhausen.
