Alexander Koester

Alexander Max Koester was born on 10 February 1864 in Neustadt, now Bergneustadt, in the Rhineland. At his parents' wishes he began an apprenticeship in a pharmacy in Wintzenheim, near Colmar, in 1882. He left that path for art, enrolling at the Academy of Fine Arts in Karlsruhe in 1885, where he studied under Karl Hoff and Claus Meyer through roughly 1896. During those years he also made extended study trips to the Black Forest, the Vosges, Munich, and Tyrol.

His career gained momentum in the early 1900s as awards accumulated: a small gold medal at the Grosse Berliner Kunstausstellung and a silver state medal in Salzburg, both in 1902, then a gold medal at the 1904 Louisiana Purchase Exposition in St. Louis for the painting "Enten," and a further gold medal from Prince Regent Luitpold of Bavaria for "Dem Ufer zu." Between 1908 and 1912 his duck paintings were shown regularly in London, Paris, and Pittsburgh, and in 1907 the King of Italy acquired one of his works. Koester was associated with the art colony at Klausen (Chiusa) in South Tyrol and eventually settled in Munich, where he died on 21 December 1932. A memorial exhibition followed at the Künstlerbund in Munich in 1933, and in 1985 the Neue Pinakothek presented "Alexander Koester, Werke aus der Schenkung Else Eckhard," drawn from a donation of his work.

Koester's reputation rests almost entirely on his duck paintings, a specialization consistent enough across four decades of production that dealers still market him under the "Enten-Koester" name. The Vienna auction house Dorotheum, drawing on the reference work by R. Stein and H. Koester, has characterized him as conservative in his handling of form but innovative in his Impressionist treatment of light and reflection in his animal compositions, while noting that his landscapes, portraits, and flower paintings deserve wider recognition on their own terms. That framing, an academically trained painter who found his most distinctive voice in a single repeated motif rendered with an Impressionist eye for reflected light, has held up consistently across gallery and museum literature from his lifetime to the present.

Koester's auction market is anchored by the best-documented high result found in research: a sale at Koller Auktionen in Zurich on 18 September 2009 for CHF 204,000, against a presale estimate of CHF 120,000 to 160,000; the exact title of the work sold could not be confirmed in available sources. That figure sits well above his typical trading range. Market summaries and recent house results, including sales at Lempertz, Dorotheum, and Im Kinsky, place most of his paintings anywhere from roughly EUR 400 up to about EUR 200,000, with many recent lots clearing between EUR 2,000 and EUR 75,000. His largest, most sought-after duck compositions command the top of that range; smaller studies and later, more repetitive works trade far lower.

There is no catalogue raisonne for Koester, so provenance, a documented "A. Koester" signature, and expertise from dealers active in his market, such as Galerie Paffrath and Galerie Schüller, carry real weight in authentication. His market is wide: the 2009 Koller Auktionen result of CHF 204,000 is a documented outlier, not a typical price, and the great majority of his paintings, particularly smaller or later duck scenes, sell for a small fraction of that figure. Subject matter matters more than it does for most artists in his market; his large, luminous duck compositions on water are consistently the works that draw premium prices, while portraits, flowers, and minor landscapes trade well below. Because a large share of his estate is concentrated at the Neue Pinakothek in Munich, major top-tier compositions rarely reach the open market, which is itself part of why the small number of high-end sales can swing so widely.
