Carlsminde in
Søllerød, Denmark, He grew up in a family where there was great interest in music, art, literature, and travel. He then studied for three years at the
Royal Danish Academy of Fine Arts in Copenhagen. and Paris. place at the
Fuglsang Manor on the isle of
Lolland. The place hosted every Summer many artists and musicians of the day in Scandinavia. In the evening, concerts were organised in the large music room. Oluf Hartmann met there among others
Edvard Grieg and
Carl Nielsen. His paintings frequently draw subjects from mythology or the Bible and mix traditional and modern styles, with classical outline and geometric composition holding figures which border abstract art. The colors he used were muted, similar to paintings by
Delacroix,
Goya and
Rembrandt. Hartmann was seen as one of the up-and-coming artists of his generation and his works were well regarded by his peers.
André Salmon published after his death in Paris a collection of ten of Hartmann's engravings together with an introduction and a biographical notice. Some of his works feature images from the
Skejten Nature Reserve at Fuglsang. Though mostly in a small format, they are powerful with bright colours and a beautiful rendering of light. It is possible that Hartmann met
Olaf Rude or other painting peers there, as Rude's parents had a farm near Fuglsang and he painted some of his most famous images from scenes at Skejten. For a time his works were forgotten, but there has been a recent resurgence of interest in his art. In his groundbreaking book on Danish art in the 20th century, art historian
Mikael Wivel singled out Hartmann as the starting point for the development of 20th century painting in Denmark. After Hartmann's death there have been regular exhibitions of his works in Denmark, Scandinavia and several times in Italy. He exhibited at the
Charlottenborg Spring Exhibition in 1905 and 1907 at
Den Frie Udstilling in 1908 and 1909. He died 16 January 1910, in Copenhagen, after an unsuccessful appendectomy. Carl Nielsen wrote
At the Bier of a Young Artist for his funeral. After his death, his siblings founded the Oluf Hartmann's scholarship for young painters. ==Selected works==
