Born in 1938 in Appenzell, Switzerland, Roman Signer worked as an architectural draughtsman before studying at the School of Art and Design Zurich, the Lucerne School of Art and Design, and the Warsaw Academy of Fine Arts. Signer is particularly known for his performance work, including “action sculptures” which involve recording experiments such as explosions and collisions that bear aesthetic results. Signer has exhibited internationally including shows at Hamburger Bahnhof in Berlin, Bonnefanten Museum in Maastricht, and Aargauer Kunsthaus in Aarau. Steidl has published his Travel Photos (2006) and Projections (2008).
