Christian Axel Dahl, known as Chrix Dahl, was a Norwegian painter and illustrator born in Kristiania (now Oslo) on 5 January 1906 and died in 1994. He worked in Norway during the first half of the twentieth century, and his interest lies in combining painting with book illustration.
The eldest son of a naval officer, he grew up in Vestre Aker and attended Skøyen School and Frogner School. He trained at the Norwegian National Academy of Craft and Art Industry under Eivind Nielsen, and at the Norwegian National Academy of Fine Arts under Axel Revold, Halfdan Strøm and Olaf Willums. He travelled through southern Europe, including Venice in 1929, and made his exhibition debut at Blomqvist in Oslo in 1930. Several of his works from the early 1930s, such as Piazzale Mercato and På broen, are held by the National Gallery of Norway, which also holds his Selvportrett of 1933.
From 1945 to 1974 he taught at the craft school where he had trained. He was active in professional organisations: secretary of the Norske Grafikere from 1938 to 1946 and chairman from 1946 to 1953, and a board member of the Oslo Kunstforening and the Kunstnernes Hus. His illustrations appeared in books by Bjørnstjerne Bjørnson, Henrik Wergeland, Mark Twain, Jules Verne and Stefan Zweig. In 1979 he was made a Knight First Class of the Order of St. Olav. He was buried at Ullern Cemetery in Oslo.
