Gustaf Fjaestad was a Swedish artist and craftsmen who worked as an assistant to Bruno Liljefors at the Biological Museum in Stockholm. Fjaestad was a technically gifted painter who mainly painted scenes of nature, but he also designed furniture for places such as the Thielska galleriet. His breakthrough came in 1898, when he co-founded the Rackstad Colony. His paintings in particular with motifs from nature became popular and were often reproduced.
Fjaestad’s work is represented at Nationalmuseum, the Gothenburg Museum of Art and the Thielska galleriet. He was married to artist Maja Fjaestad.
