Roman Signer: Collection Hauser und Wirth

Swiss artist Roman Signer has been redefining sculpture for more than 40 years and is now regarded as one of the finest representatives of Process and Conceptual art. He produces elementary dynamic sculptures and installations, also known as time sculptures for their preoccupation with the transformation of materials and objects through time. In his actions, acceleration and change are part of the creative process and he uses photography and moving image to document his work.
