On May 19, 2010, Dirk van Sliedregt died at the age of ninety. He worked as an architect, interior architect, furniture designer and teacher. He belonged to the generation of designers such as Friso Kramer (*1922), Wim Rietveld (1924-1985), Kho Liang Ie (1927-1975), Benno Premsela (1920-1997) and Hein Stolle (1924-2006), who began their work shortly after World War II and fairly quickly became guiding principles within design in the Netherlands. After training as a furniture maker, Van Sliedregt worked for various furniture factories and, in the evenings, studied interior design at the Academy of Visual Arts and Technical Sciences in Rotterdam. By his own admission, he was influenced in his design more by Willem Penaat (1875-1957) and Kaare Klint (1888-1954) than by Charles Eames (1907-1978) or Gerrit Rietveld (1888-1964). In the late 1940s he was asked to develop furniture for the Jonkers brothers in the Frisian town of Noordwolde. These wanted to breathe new life into the wickerwork industry established there as early as the nineteenth century after the war. The designs came about in direct cooperation with the workers in the workshops. The models were elaborated on the basis of rough 1 : 1 sketches on packing paper. Characteristics were the simple lines of the models, the distinction between the supporting construction and the seating form, partly through the use of steel tube in the design, and the great attention paid to seating comfort. Partly due to publications in the then-leading magazine Goed Wonen, where these furniture were touted as simple, visually non-polluting and inexpensive, his furniture became popular and enjoyed a special reputation. For years, for example, the auditorium and restaurant of the Stedelijk Museum in Amsterdam featured slender chairs by his hand. Van Sliedregt also designed several models for the firm Pastoe. His practice as (interior) architect included mainly residential houses, bookstores, pharmacies and public buildings. In the furnishings of various town halls, he often collaborated with architect Theo Verlaan (1912-1997), such as in Dalfsen, Genemuiden, Putten, Losser and Heino. In addition, Van Sliedregt was primarily a teacher. From 1949-1955, he taught architectural design at the Academy for Art and Industry (AKI) in Enschede, along with Aldo van Eyck (1918-1999), Jan Rietveld (1919-1986) and Joop Hardy (1918-1983), among others. In 1955 he exchanged this position for teaching at the Gerrit Rietveld Academy in Amsterdam, for which he again recruited Jan Rietveld, among others, as a lecturer. He remained there as a teacher until 1978, when he was asked to set up a new Christian Academy of Visual Arts in Kampen (today's ArtEZ college of arts in Zwolle). Of this he was director until his retirement in 1985. With his down-to-earth functional approach to design, Van Sliedregt was of great importance to the development of (furniture) design in the Netherlands. In his teaching, he emphatically instilled this vision in his students. Several hundred (interior) architects were trained by him. His students at the Rietveld Academy included Peter Vöge (1945-2003), Mart van Schijndel (1943-1999), Gijs Bolhuis (*1946), Kees Spanjers (*1954) and Radboud van Beekum (*1950). In 2001, a retrospective exhibition of his furniture designs was held at the Nationaal Vlechtmuseum in Noordwolde. In 2003, an armchair from 1959 was reissued by the Lensvelt company.
