History

The department was created in 1977, as a merger of Department of Numerical Mathematics at the Department of Mathematics and the Department of Cybernetics at the Department of Physics. However, the history of computer science at the university goes further back than that. In 1958, the university had received its large machine "FREDERIC", and Harald Keilhau held a programming course for those who needed the machine for their research. Ernst S. Selmer also gave a lecture on data processing from the mid-fifties, and from the sixties the first competence-giving courses in programming (based on
