Colin Campbell Cooper, Jr. (March 8, 1856 – November 6, 1937) was an American Impressionist painter, perhaps most renowned for his architectural paintings, especially of skyscrapers in New York City, Philadelphia, and Chicago. An avid traveler, he was also known for his paintings of European and Asian landmarks, as well as natural landscapes, portraits, florals, and interiors. In addition to being a painter, he was also a teacher and writer. His first wife, Emma Lampert Cooper, was also a highly regarded painter.
