Erich Hauser (15 December 1930, Rietheim – 28 March 2004, Rottweil) was a German sculptor.
In dealing with metal he was influenced by contemporary informal painters of the 1950s. At first, his steel sculptures still showed noticeable marks of processing. Later he opted for smooth surfaces. Since 1962 he worked with industrially pre-fabricated steel plates. At the same time, he dealt with basic geometrical structures and technical structural elements, which were characteristic of Hauser’s first autonomous works.
He transformed composed surfaces into hollow sculptures to be viewed from all sides, showing edgy burrs and caves. The sculptures cannot be walked-on. Hauser assembled the metal elements in such a way that they finally became regular hollow bodies. Thus he created spheres, cubes and tetrahedrons.
It is significant of these works that they seem likely to break or fall to pieces or be in risky balance.
