(September 18, 1844?CJanuary 13, 1934) was an American artist, best known for a series of nine paintings of anthropomorphized dogs. Born in upstate New York to abolitionist Quaker farmers, Coolidge was known to friends and family as "Cash." While he had no formal training as an artist his natural aptitude for drawing led him to create cartoons for his local newspaper when in his twenties. He is credited with creating Comic Foregrounds, life-size cutouts into which one's head was placed so as to be photographed as an amusing character. In 1903, Coolidge contracted with the advertising firm of Brown & Bigelow of St. Paul, Minnesota, to create sixteen oil paintings of dogs in various human poses.
