Carel Scholten
Carel S. Scholten (* 1925 in Amsterdam ; † December 5, 2009 ) was a Dutch physicist and computer pioneer.
Scholten went to the Vossius Gymnasium in Amsterdam and studied physics at the University of Amsterdam from 1945 to 1952 . From 1947 he built the relay computer ARRA I (completed in 1952) at the Mathematical Center in Amsterdam with his friend and fellow student Bram Loopstra . He had to do his military service from January 1948 to September 1950. The first version ARRA I was a failure, in contrast to the successor version, which was created with the participation of Gerrit Blaauw , who had returned from the USA (ARRA II). In 1954 he and Loopstra built the ARMAC computer, which used transistors. Edsger W. Dijkstra was responsible for the software , with whom Scholten worked on a friendly basis for over 30 years. From 1959 he worked with Loopstra at Electrologica (Amsterdam, Rijswijk from 1964 ), which was founded by the Mathematical Center together with the insurance company Nillmij (the financier) and which was taken over by Philips in 1968 . Both built the Electrologica X1 computer there, which came on the market in 1958, and 40 copies of which went mainly to universities by 1964 (it was developed at the Mathematical Center and carried out its first calculations in 1957). He used transistors and ferrite core memories. In 1964 the successor model EL-X8 followed. At the Electrologica X8 there was also the possibility of time sharing based on ideas from Dijkstra. In 1979 he moved to the Philips Natuurkundig Laboratorium in Eindhoven, where he stayed until 1985.
In 1991 he received an honorary doctorate from the TU Eindhoven .
