After attending the elementary school in Ljustorp, his family moved to Sundsvall, where he worked in a sawmill until he was fourteen.
In 1901, he became an assistant at the local newspaper and joined a group of amateur artists headed by Helmer Osslund.
Thanks to financial support from Karl Nordström, he was able to begin studies at the Artist's Association School (Konstnärförbundets skola), from 1907 to 1908, then went to Paris, where he took lessons from Henri Matisse.
Back in Sweden, he was one of the first members of a short-lived group called "De Unga [sv]" (The Young), which applied Expressionist techniques to Swedish motifs.
His works may be seen at the Moderna Museet,[3] Nationalmuseum,[4] Prins Eugens Waldemarsudde,[5] and the Gothenburg Museum of Art.
