Jan Leupen (1901-1985) Jan Leupen attended the Technische Hogeschool in Delft from 1920 to 1926. In 1927 he receives an appointment as deputy architect at the Buildings Department of the Public Works Department in Amsterdam. His first independent commission is the design for a session building of the Municipal Medical and Health Service, the GGD, on Eerste Helmersstraat in Amsterdam. This was followed by several 12-class school buildings and the GGD building in Florapark in Amsterdam. In 1938 he designed the traditional Aula building with fan-shaped floor plan at the cemetery 'De Nieuwe Ooster' in Amsterdam, which was completed in 1939. Due to the Second World War, completion came to a standstill and painter Albert Muis was not able to install his murals in the hall and auditorium until after the war.In 1939, Van Leupen was commissioned to work out new construction plans for a main building for the then Municipal Telephone Service, but these plans also had to be shelved due to the war. In 1947, Leupen is appointed head of the Buildings Department of the Public Works Department at the City of Amsterdam, and in that capacity he still realizes the head office for the Municipal Telephone Service on Pieter de Hooghstraat in Amsterdam (1955). Glass art representations by Wim Wagemans symbolically refer to the telephone service. Van Leupen also designed several school buildings, including the Spinozalyceum on the Peter van Anrooystraat in Amsterdam (1957, in collaboration with F.H. Gerretsen), which is considered one of his most important works. The design with an open stairwell, with long, brightly lit corridors and a special auditorium is tailored to Dalton secondary education, in which students work independently a great deal. The hall will feature a monumental mural by Albert Muis and, in the entrance portal, a mosaic by artist Nicolaas Wijnberg. Van Leupen's last and most controversial building is the University Library of the University of Amsterdam (1966, in collaboration with F.H. Gerretsen, N.G. Mayer and S. van der Woude) on Het Singel. The modern, businesslike building is in obvious contrast to the surrounding seventeenth-century canal houses. The archival materials at the NAI include, in addition to a maquette of his now demolished PTT main building on the Pieter de Hoochstraat in Amsterdam, his publication Bouw en inrichting van scholen van voorbereidend onderwijs, kinderbewaarplaatsen en kinderdagverblijven in Tijdschrift voor Sociale Geneeskunde (June 1932) and his 1979 manuscript Het proces van de creatieve daad in de kunst. There is also a sketch plan "open-air race school" with no date. Note: Jan Leupen's oeuvre has not been (fully) inventoried. Education: Delft University of Technology/1920-1926
