Biography
Biography
Olaf Isaachsen studied at Norwegian National Academy of Craft and Art Industry and Kunstakademie Düsseldorf. Training under Adolph Tidemand and Thomas Couture is recorded. The recorded working language is Norwegian. Subjects and genres recorded for the work are portrait. Work by Olaf Isaachsen is recorded in the collections of Finnish National Gallery, National Museum of Art, Architecture and Design and KODE Art museums and composer homes.
He was born in Mandal in Vest-Agder county Norway. Isaachsen belonged to a branch of an affluent and educated merchant family from Kjos in Kristiansand. He was the son of jurist Daniel Peter Christian Isaachsen, grandson of politician Isaach Isaachsen and great-grandson of Daniel Isaachsen (1744-1813), a Norwegian shipbuilder. He was the uncle of physicist Daniel Isaachsen, scientist Haakon Isaachsen (1867–1936), painter Herman Willoch and naval officer Odd Isaachsen Willoch. He attended Nissens Latin School in Christiania (now Oslo). He later studied under Joachim Frich and Johannes Flintoe at the Royal School of Drawing from 1850, in Düsseldorf from 1854 to 1859, and in Paris under Thomas Couture (1859-1860) and Gustave Courbet (1861-1862). After a visit to Italy he returned home in 1864 with a view to becoming an artist with a strong focus on archeology and history. He ultimately settled in Kristiansand, although with frequent periods spent abroad. His artistic style reflected naturalism and in later years impressionism. Isaachsen was regarded as one of Norway's more prominent artists and great colourist with motives of the coast landscape of Southern Norway. He also painted a wide range of portraits. Moreover, he found a full valid artistic expression in Setesdalen. His art often reflected the valley's distinctive culture. He is represented with 24 works in the National Museum in Oslo (NM), former National Gallery of Norway. The Regional Museum in Kristiansand, Sørlandets Kunstmuseum (SKMU) has 58 works.
Personal life
Personal life
Isaachsen was a knowledgeable and courteous man, a mixture of observation and locals, who spoke fluent German, Dutch, English, French and Italian. He was married in 1864 to Antonie (Toni) John Prehr (1838-1870). The couple had four children – William (1865-1942), Eivind (1866-1926); Johanna Marie (1867-1872) and Harald (1869-1942). His wife died of tuberculosis when only 32 years old. Two years later his four-year-old daughter Johanna Marie died of diphtheria, and he was left with three small boys. He was the paternal grandfather of Sigurd Daniel Isaachsen Willoch, an art historian and director of the National Gallery of Norway.
