Regnecentralen
Regnecentralen, or RC for short, was the first Danish computer company, founded on October 12, 1955. Through the 1950s and 1960s they designed a series of computers, originally for their own use, and later to be sold commercially. Descendants of these systems sold well into the 1980s. They also developed a series of high-speed paper tape machines, and produced Data General Nova machines under license.
==Genesis==
What would become RC started as an advisory board formed by the Danish ''Akademiet for de Tekniske Videnskaber'' (''Academy of Applied Sciences'') to keep abreast of developments in modern electronic computing devices taking place in other countries. After several years in the advisory role, in 1952 they decided to form a computing service bureau for Danish government, military and research uses. Led by Niels Ivar Bech, the group was also given the details of the BESK machine being designed at the Swedish Mathematical Center (Matematikmaskinnamndens Arbetsgrupp).
The group decided to build their own version of the BESK to run the bureau, and formed Regnecentralen in October 1955 to complete and run the machine. The result was the DASK, a vacuum tube-based machine that completed construction in 1956 and went into full operation in February 1957. DASK was followed in 1961 by the fully transistorized GIER, used for similar tasks. GIER is an acronym for "Geodætisk Instituts Elektroniske Regnemaskine" (Institute of Geodetics Electronic Calculator) and was introduced there on September 14, 1961. GIER proved to be a useful machine, and went on to be used at many Danish universities. Bech also sold GIER machines to the Eastern Bloc nations, starting with Czechoslovakia, Hungary, Poland and Bulgaria, and later Romania, the East Germany, and Yugoslavia.
RC was also home to Peter Naur, and DASK and GIER became particularly well known for their role in the development of the famous ALGOL programming language. After the first European ALGOL conference in 1959, RC started an effort to produce a series of compilers, completing one for the DASK in September 1961. A version for the GIER followed in August 1962. Christian Andersen, another RC employee, wrote the first introductory text on the language, ''Everyman's Desk ALGOL'', in 1961.
