Alexander Max Koester (10 February 1864, Bergneustadt - 21 December 1932, Munich) was a German landscape and animal painter.
After completing his training there, he pursued his own interests; enrolling at the Academy of Fine Arts, Karlsruhe, where he studied with Karl Hoff and Claus Meyer [de].
He spent the decade from 1885 to 1895 making study trips: to the Black Forest, the Vosges, Munich, and Tyrolia.
[1] While visiting the town of Klausen, a gathering place for artists, he met Isabella Kantioler, the daughter of an innkeeper.
In 1902, he won a small gold medal at the Große Berliner Kunstausstellung; and another at the Louisiana Purchase Exposition in 1904.
