Nieweg was born in
Steenwijkerwold and studied interior design at the
Academy of Fine Arts in
Rotterdam. His teacher Frieda Koch brought him into contact with ceramics. As an artist Nieweg is autodidact. From the 1960s to the 1980s Nieweg lived and worked in
Giethoorn, where he ran his own pottery studio. In the 1990s he moved to
Monchique in
Portugal, where he built several large ovens. He died in
Portugal a few years later, at the age of 67. Much of Nieweg's work was done in ceramics, examples are the reliefs he made for
Zwolle and
Heino. == Works ==
