Robert Rauschenberg was an American artist who worked as a painter, sculptor, photographer, paper-maker, and performer. Rauschenberg is especially known for his "combines," paintings that incorporated objects onto their surface, creating a hybrid between painting and sculpture.
Hans Hofmann was born in Germany but is considered an American painter. His work is generally characterized as abstract expressionism, and he is also known for his push/pull spatial theories, which suggests an alternative to one point perspective. Instead, the use of color, shape, and light could create a push and pull effect that creates the illusion of space and motion.
