Born in Stockholm, from 1877 to 1882, Björck was a student of Edvard Perséus at the Academy where his paintings included Loke fängslas af asarne , Gustaf Vasa inför kung Hans and Den förlorade sonens återkomst which was awarded the Royal Medal. In 1883, Björck was awarded a travel scholarship. He spent the winter of 1883-84 in Paris. The following winter, he went to Munich where he painted a few portraits, including a full-length painting of his wife. In the spring of 1885, he moved to Venice and, in the autumn, to Rome where he painted the large portrait of Susanna and Romerska smeder . In 1887, he completed a number of paintings including the Veneziansk saluhall , and Lördagsmässa i Markuskyrkan. After summer stays at Skagen in Denmark in 1882, 1883 and 1884, he finally settled in Stockholm in 1888 where he concentrated on portraits. These include several of King Oscar ; Crown Prince Gustaf, The Artist's Wife'' and Baron . In addition, he completed a few landscapes, a couple of genres and various decorative paintings. From 1889, he was a member of the Academy and its teaching staff and in 1898, he became a professor. Björck was Commissar for Art at the Stockholm Exposition in 1897, for the Baltic Exhibition in 1914 and for the Swedish exhibition in London in 1924. Björck's earliest portraits were influenced by Georg von Rosen and his pictures from Skagen reflected the influence of Danish artists, especially Peder Severin Krøyer. In many of his characteristic works, he depicted the Swedish middle class of his times.
Summers in Skagen
Björck was encouraged to go to Skagen in 1882 by P.S. Krøyer whom he had met in Paris and for whom he showed great admiration. He immediately became attached to the artists' community there, especially Michael Ancher, his wife Anna and Holger Drachmann. It was not just the Skagen landscape that attracted him but equally the warmth and hospitality of the artists themselves. Björck spent several summers there, completing some of his best paintings under the influence of Krøyer and the French Naturalism movement. Oscar Björck can be seen drinking champagne in Krøyer's famous painting Hip, Hip, Hurrah! which shows several of the Skagen Painters celebrating in the Anchers' garden.
