Aldo van den Nieuwelaar (1944-2010) was a Dutch designer and interior decorator. He studied at the Academy of Fine Arts in Breda. After his graduation in 1969 he founded his own design studio, stimulated by Benno Premsela. Inspired by Gerrit Rietveld, De Stijl and Bauhaus, he designed furniture, rugs, lamps, light sculptures with strict minimalist geometric shapes.
In 1968, Van den Nieuwelaar designed a series of innovative fluorescent lights in curved steel tubes, in white and chrome. Most of his items however were only produced in very limited productions, making these items rare. His designs have been exhibited at the Stedelijk Museum in Amsterdam, Museum Boijmans Van Beuningen in Rotterdam, the Van Abbemuseum Eindhoven and the Museum of Modern Art in New York.
