Armin Hansen, a native of San Francisco, was a prominent American painter of the en plein air school, best known for his marine canvases. His father Herman Wendelborg Hansen was also a famous artist of the American West. The younger Hansen studied at the California School of Design in the Mark Hopkins Institute of Art (now the San Francisco Art Institute) and in Europe. He achieved international recognition for his scenes depicting men and the sea off the northern coast of California. In 1913 he first visited Monterey, where he eventually settled to teach and to find inspiration in the small fishing community and in the art colonies on the Peninsula. He painted in oils and watercolors and perfected his skills in graphic arts, especially etchings. Hansen became enamored of creating marine scenes, particularly involving man's relationship with the sea. Hansen became extremely active in large Carmel-by-the-Sea art colony. He was not a founder of the Carmel Art Association in 1927, but eventually joined that organization and served as president and on the board of directors. He was the co-founder of the Carmel Art Institute in 1938. In the early 1920s Hansen associated with members of the Society of Six. By this time Hansen was not only one of the most well known California artists, but arguably the best teacher of the era.
