Dutch draughtsman and sculptor.
He trained at the Academie voor Beeldende Kunsten (1954–8) in Rotterdam. In 1961 he had his first group exhibition in Gorcum with Jan van Munster (b 1939) and Henk Visser (b 1940), in which he showed polychrome wood reliefs influenced by Piet Mondrian, Ben Nicholson and Hans Arp. From 1962, apart from wall reliefs, he produced sculptures. In addition to using his two-colour method he sometimes worked in monochrome, black or white. From 1964 until 1966 he made reliefs with compilations and displacements of the same geometric shape. His work began to show a certain affinity with that of Jan van Schoonhoven; both artists shared a partiality for white. From 1965 he produced mainly monochrome work in which he experimented with contrasts of light and shadow. His sources of inspiration included freemasonry. Between 1965 and 1970 he used polyester in wall reliefs. In 1965, during a trip to New York, he got to know the work of Frank Stella and Elsworth Kelly, and in 1966 his first retrospective exhibition was held at the Stedelijk Museum, Schiedam. Around this time he also suffered a mental crisis, which developed again in subsequent years. In his last four years he produced more than half of his total oeuvre. From 1970 he made transparent drawings and wood reliefs with sawn grooves. In 1971 he designed a relief for the two long corridor walls of the Kröller-Müller Museum, Otterlo.
