Sigrid Hjertén (1885-1948) was born in Sundsvall and was a painter. She was a student of Henri Matisse in Paris. In 1911 she married the artist Isaac Grünewald. Their works had much in common in form, lines and warm and cold colors coming together. However, Sigrid Hjertén's art differed from Grünewald's by being much milder in color with a more stark composition. From the 1920s, Hjertén's motifs consisted of French cityscapes, landscapes and portraits, but the minor tone and concern emerge more during the 1930s, and similarities to Van Gogh's oblique strokes of color can be seen. In 1937, Sigrid Hjertén stopped painting due to increasing mental illness.
