Rudolf Koller (21 May 1828 – 5 January 1905) was a Swiss painter.[1] He is associated with a realist and classicist style, and also with the essentially romantic Düsseldorf school of painting.[2] Koller's style is similar to that of the realist painters Gustave Courbet and Jean-Baptiste-Camille Corot. Considered Switzerland's finest animal painter, Koller is rated alongside George Stubbs, Rosa Bonheur and Théodore Géricault. While his reputation was based on his paintings of animals, he was a sensitive and innovative artist whose well-composed works in the "plein air" tradition, including Swiss mountain landscapes, are just as finely executed.[3][4]
He has been described as "the painter of the Swiss national animal", because of his paintings of cows in Swiss landscapes.[5] He is considered, along with Frank Buchser and Gustave Eugène Castan , to be one of the most important Swiss painters of the 19th century.[6] The Gotthardpost, or The St Gotthard Mailcoach, is one of his most famous paintings. It depicts a mail coach, drawn by white horses, speeding along a mountain road.[2][7]
