Hans Petri (Weerselo, 1919 - Dordrecht, 1996) graduates from the Rotterdam art academy, after which he works as a graphic artist and sculptor. After the reconstruction he received many commissions for public space, especially in Dordrecht and Rotterdam, but also elsewhere in the country. He mainly worked in stone, later sometimes in concrete. After creating freestanding sculptures and reliefs, he has been active as an environmental designer, with his 'eggs' at Erasmus University being an important example. These and other works have been demolished, several others still remain in the public space. In 2001 he was posthumously given a major retrospective exhibition in the Dordrechts Museum.
