Siri Derkert was born in in Stockholm and is known as a graphic artist, visual artist and sculptor. Derkert studied at Althin’s School of Painting, the Royal Swedish Academy of Fine Arts and the adult school for women run by the Fogelstad group. She also studied abroad in Italy, Spain and France. Derkert is famous for working with all types of materials; her style was Expressionistic while at the same time being Cubist and Fauvist. The artist encountered Cubism during her Paris studies in 1913, after which she painted portraits and still lifes in Facet Cubism style. Her paintings are bright, cool and elegant, while the facets in her pictures were painted in darker shades.
Derkert took a ten-year break from her art. She did not begin painting again until the mid-1920s, this time in a realistic style which departed from her earlier painting. The artist used her three children as models for her paintings, portraying them in various domestic situations - both calm and lively. In 1933 her art took a new direction in which her idiom expresses insecurity and anxiety. Her paintings became increasingly abstract, consisting of just a few streaks. This obliteration of form was gradually replaced by a new interest in sculpture during the war years. In 1944 Derkert had a breakthrough after meeting with the Fogelstad group at the adult school for women. The group inspired Derkert and instilled a new desire to experiment. Her art returned to Cubism and Derkert began to use new materials such as collage and primitive drawing art that was carved in metal or sandblasted into concrete. Derkert’s concrete art can be viewed at the Östermalm metro station in Stockholm. In 1960, Moderna Museet in Stockholm held its first solo exhibition for a woman who had come to be one of Sweden's most important artists: Siri Derkert.
