Louis Macouillard (1913 – 1987) was an American painter born in San Francisco, California. He is best known for his bright, bold watercolor depictions of local cityscape scenes of the Bay Area completed from the 1930’s to the 1950’s. During World War II, he was stationed in the South Pacific and produced many watercolors while away at war, some of which appeared in Life magazine at the time. After the war, he continued to paint representational transparent watercolor paintings of cityscape scenes and landscape subjects in the Sonoma County area. Some of his most famous pieces include Summer Fog, Fisherman’s Wharf, and Telegraph Hill, all completed upon his return to the United States.
