Passages:
Olav Engebrigtsen (15 January 1878 – 15 April 1962) was a Norwegian painter and illustrator.  He was born in Kristiania.  He studied art with Harriet Backer for four years, with Kristian Zahrtmann in Copenhagen, and with Henri Matisse in Paris.  From 1911 to 1940 he was appointed as illustrator for the newspaper "Tidens Tegn".  Among his book illustrations are Margrethe Munthe's songbooks "Kom skal vi synge", Bernhard Stokke's children's book "Dag fra skogene", and contributions to various basal readers for primary school.  He is represented at the National Gallery of Norway, in Oslo Bymuseum and in Riksgalleriet.  He died in Oslo in 1962. Ossian Elgström (1883 – 1950) was a Swedish illustrator and writer.  He was a brother of writer and visual artist Anna Lenah Elgström.  Elgström studied at the Royal Swedish Academy of Arts from 1906 to 1907, and then with Kristian Zahrtmann in 1907 and with Christian Krohg in 1908.  He contributed to the magazines "Strix", "Söndags-Nisse" and "Puck".  He collected folkloristic material from Siberia, Greenland and Lappland, which he used in his books.  Among his books are "Lapska myther" from 1914, "Lappalaiset" from 1919, and "Karesuando-lapparna" from 1922. Hans Ødegaard (30 May 1876 – 1 March 1943) was a Norwegian painter.  He was born in Norderhov.  He studied painting and drawing with Brynjulf Bergslien, Kristian Zahrtmann and Johan Nordhagen.  Among his paintings at the National Gallery of Norway are "Skraphandel i Vaterland " from 1903, and "Fra Tvedestrand" from 1919.  He was responsible for the presentation of elder Norwegian art at the 1914 Jubilee Exhibition at Frogner in Kristiania.  The presentation of painters such as Lars Hertervig, Mathias Stoltenberg, Peder Balke and Johannes Flintoe gave these artists a more prominent position in the history of Norwegian art. Poul Simon Christiansen, frequently referred to as Poul S. Christiansen (20 October 1855, Rolfsted, Funen – 14 November 1933, Copenhagen) was a Danish painter who developed a Colourist style under Kristian Zahrtmann and as a result of his appreciation of the works of Paul Gauguin and Vincent van Gogh.  He painted landscapes and religious works, many of which became popular as reproductions. Folmer Bonnén (1885–1960) was a Danish painter and journalist.  He was one of the founding members of the grouping of modern artists known as De Tretten where, in 1909, he exhibited a large colourful painting "Ungdom i aftensol" (Youth in the Evening Sun), causing quite a stir.  Kristian Zahrtmann immediately supported the daring work, rewarding Bonnén with a stipendium.  As can be seen from his solo exhibition in 1942, Bonnén's later paintings were much more subdued as, no doubt under the influence of the Nazis, he sought to contribute to "national culture".  Indeed, during the Second World War, he worked as a journalist for the Nazi newspaper Fædrelandet. The Funen Painters or Fynboerne were a loose group of Danish artists who formed an art colony on the island of Funen at the very beginning of the 20th century.  They were strongly influenced by Kristian Zahrtmann who taught at the Artists Studio School in Copenhagen from 1885 to 1908.  Like Zahrtmann, they abandoned the traditions of the Danish Academy and ventured into Naturalism and Realism. Peder Henrik Kristian Zahrtmann, known as Kristian Zahrtmann, (31 March 1843 – 22 June 1917) was a Danish painter.  He was a part of the Danish artistic generation in the late 19th century, along with Peder Severin Krøyer and Theodor Esbern Philipsen, who broke away from both the strictures of traditional Academicism and the heritage of the Golden Age of Danish Painting, in favor of naturalism and realism. Johannes Martin Fasting Wilhjelm (7 January 1868 – 22 December 1938) was a Danish painter.  Strongly influenced by Kristian Zahrtmann, he painted bright, colourful landscapes while travelling in Italy.  His works also include religious paintings and portraits.  He frequently visited the artists' colony of Skagen in the north of Denmark where he painted scenes of the dunes and beaches. Peder Severin Krøyer ['peːdə 'seveʁin 'kʁojə] (23 July 1851 – 21 November 1909), professionally known as P. S. Krøyer, was a Danish painter.  He is one of the best known and beloved, and the most colorful of the Skagen Painters, a community of Danish and Nordic artists who lived, gathered, or worked in Skagen, Denmark, especially during the final decades of the 19th century.  Krøyer was the unofficial leader of the group. Theodor Esbern Philipsen (10 June 1840, Copenhagen - 3 March 1920, Copenhagen) was a Danish painter of Jewish ancestry; known for landscapes and animal portraits.  He also did small figures in wax and clay.
