In 1931, Theodore Brauner joins the Surrealist group Alge in Bucharest. In 1934, he creates his first photographs without the use of a camera. He calls these works Solarfixes (they are not photograms, as he eliminates not only the camera, but also the darkroom).

Brauner leaves Romania in 1942 and arrives in Israel in 1944. His Solarfixes are exhibited for the first, and the last, time in Jerusalem (1955). These artworks on light sensitive paper, he considers his most important achievement, though his accomplishments in photography proper also make him one of the great practitioners of the art.
