Theodor Philipsen was born at
Copenhagen to a cultured merchant family and learned to draw at an early age. At first, however, he was primarily interested in animals, so he went to study agriculture at his uncle's estate near
Slangerup. In the 1860s, one of his brothers introduced him to the painter,
Hans Smidth, which made him decide to become an artist. He began his studies at the
Royal Danish Academy of Fine Arts with
Carl Bøgh and later came under the influence of
Frederik Vermehren. In 1873, he was awarded the for his painting of horses swimming. In the 1880s, he began painting en
plein air and began to show some elements of
Impressionism. At the age of thirty-five, concerned that his images were not realistic enough, he went to Paris to study with
Léon Bonnat. There, he practiced intensive
croquis drawing; to capture the basics of position and movement. He also obtained knowledge of the radical trends in French art through his friend,
Rémy Cogghe, with whom he spent some time in Spain and Italy. This all came together in a distinctive style. His favorite places for painting were
Saltholm and
Amager. In the winter of 1884–1885,
Paul Gauguin made a visit to Copenhagen. Philipsen approached him for some advice and was shown how to use small brushes with quick, firm strokes. They remained friends for life. In 1890, he received the
Eckersberg Medal. Around 1905, he began to suffer from an eye disease that interfered with his ability to paint. In 1915, he was awarded the
Thorvaldsen Medal. He is generally credited with establishing Impressionism as an important aspect of Danish painting. He died in Copenhagen and was buried at
Holmen Cemetery. ==Selected paintings==
