Sven Birger Sandzén (February 5, 1871 – June 22, 1954), known more commonly as Birger Sandzén, was an American painter best known for his landscapes. He produced most of his work while working as an art professor at Bethany College, Lindsborg, Kansas.
Sandzén was born in Blidsberg, Ulricehamn Municipality, Västra Götaland County, Sweden, the son of a Lutheran minister and his wife, an accomplished watercolorist. A protégé of Anders Zorn, Sandzén showed an interest in art from an early age, and at the age of 10 joined Cathedral School (Katedralskolan) situated in Skara, to study art under the tutelage of Olof Erlandsson, a graduate of the Royal Swedish Academy of Arts. After graduating in 1890, Sandzén studied for a short time at the University of Lund before moving to . It was his intention to enroll at the Royal Swedish Academy of Arts. However, the waiting list proved too long for him. Instead, he sought out and joined a group of young artists who were studying under Anders Zorn, Richard Bergh and Per Hasselberg. This group would later be known as the Artists League (Konstnärsförbundet).
At the end of his studies, Zorn and Bergh recommended that Sandzén complete his painting studies in Paris. In 1894, Sandzén left Stockholm to study under Edmond Aman-Jean who introduced Sandzén to pointillism. Aman-Jean was closely associated with Ernest Laurent and Georges Seurat in promoting impressionism. Sandzén’s early work displays these influences, along with a tonalist approach.
