In 1962, he was invited to apply for a position as a
mathematician at CERN in
Geneva, Switzerland, and the family moved there. In 1967 Beck was invited to work at the
Argonne National Laboratory near
Chicago in the United States, and the family moved to
La Grange, Illinois . At Argonne Beck did some pioneering work on pattern recognition devices for
bubble-chamber photographs. The machines for doing this involved interactive human interfaces. Activity at CERN in the meantime focussed on the construction of the
Super Proton Synchrotron (SPS), and in 1972 Beck was invited back to Europe to design and build the SPS control room and its hardware and software in the environment of a revolutionary multicomputer control system being constructed by a group under
Michael Crowley-Milling. In 1973 he published a CERN document, along with his colleague
Bent Stumpe, outlining the concept for a prototype
touchscreen as well as a multi-function computer-configurable knob, both of which found their way onto the consoles of the finished control room. The CERN touchscreen was arguably the first practical device of its kind and used a matrix of transparent capacitative pads above a
cathode-ray tube. Beck began post-graduate studies at the
Université Louis-Pasteur in
Strasbourg, France. His doctoral thesis, presented in 1976, was an expanded version of the 1973 CERN paper, this time also describing the control philosophy, which allowed skilled operators to design their own interface methods, and the various devices (including the knob and the touchscreen, the
video wall, and a switchable pool of display devices). In 1983 he moved back to Illinois for two years, this time to work at the
Fermilab in
Batavia before returning once more to CERN to work on the
Aleph detector. == Later life and retirement ==
