Frans de Boer (Amsterdam, 1942) and Marja Lichtveld (Velsen, 1941) both attended the Rietveld Academy in Amsterdam. For a long time they made kinetic objects: objects with a moving element. Over time, they processed high-gloss materials, so that the movement of passers-by was reflected. Their work consists of abstract forms, which can refer to the history of the place where the statue stands. The couple regularly receive commissions for the realization of monumental work in the public space. Space and light are important elements in their work.
