Dutch artist, born in Paramaribo, Suriname. From 1957 onwards he worked as an artist in Amsterdam. He provides no biographical information, gives no interviews and does not permit reproduction of his work. He only says that ‘the work provides the interviews, writes the biography’. Since 1960 he has been preoccupied with the idea of measurement and the relationship to the body’s movements. The series of drawings this way brouwn, made from 1961 onwards, was based on directions provided by passers-by. These were then impressed with a printed rubber stamp bearing the title. including obsolete ones. For instance, in an exhibition at the Centro Andaluz de Arte Contemporáneo in 2005 he used the old Castilian foot abolished in 1849 when the metric system was made compulsory in Spain. R. H. Fuchs writes of him: ‘The work is not imagination; it is fact’ (Dutch Painting, 1978).
