Carl Gustaf Theodore Olson (1875-1952) was an American artist known for his landscapes and seascapes. Born in Sweden, he studied there with Peter Roos and later settled in the Boston area, where he was a member of the Copely Society. He was active as an artist in Massachusetts and Michigan. His painting style is characterized by the Impressionist tradition of using broad expressive brushstrokes to depict scenes. In many of his scenes, he used exotic purples and blues to accent the local color. He also employed the technique of atmospheric perspective in his work.
