Sven Havsteen-Mikkelsen (16 September 1912, Argentina – 14 February 1999, Ærøskøbing) was a Danish painter who is remembered for his old Nordic landscapes, his church decorations and his woodcuts.
After his parents, Johan Theodor Havsteen and Ella Holm-Jensen, divorced, Havsteen-Mikkelsen was brought up by the polar explorer Ejnar Mikkelsen. He studied art under Olivian Holm Møller (1929), Fritz Syberg (1929–1932), P. Rostrup Bøyesen (1932–1933) and Oluf Høst (1932–1933). He also spent short periods at the Norwegian Academy under Per Krohg (1933–1934) and at the Danish Academy under Elof Risebye (1942–1943).
Havsteen-Mikkelsen's art and interests were deeply rooted in the Nordic countries. Under the influence of Ejnar Mikkelsen and thanks to early voyages to the Faroes, Iceland and Greenland, he was confronted while still young with subjects he would maintain throughout his life. He became especially interested in the age-old landscapes of the North, still free of the detrimental effects of civilisation. In his youth, Havsteen-Mikkelsen became acquainted with the Funen Painters where he also learnt the art of woodcut, a technique he would later use to illustrate books on Nordic literature. At the Academy in Oslo, his studies of stave church decoration developed his interest in sacred art.
After travelling widely outside Denmark, Havsteen-Mikkelsen settled first on Tåsinge and later on Ærø from where he toured the Danish countryside with Martin A. Hansen, Ole Wivel and Regin Dahl. From the 1950s, he became a central figure for church decoration in Denmark, completing altarpieces and religious works which often harmonised with existing Renaissance art. His work extended to stained glass windows which he often created with his son, the architect Alan Havsteen-Mikkelsen or with Mogens Frese. His landscapes from the Faroes and Iceland often depict early Christian communities but they are always free of human figures who are only to be found in his Biblical works. Among his landscapes depicting early Nordic cults are Askestorm, Island (1955) and Beinisvörd, Færøerne (1957). His portraits are often inspired by members of his family with 25 paintings of his wife Pam.
