Seymour Fogel was an American artist whose artistic output included social realist art early in the century, abstract art and expressionist art at mid-century, and transcendental art late in the century. His drive to experiment led him to work with expected media – oil paints, watercolors, and acrylics – as well as unconventional media such as glass, plastics, sand, and wax.
