Bent Stumpe

Bent Stumpe (born 12 September 1938, Copenhagen, Denmark) is a Danish electronic engineer who spent most of his career at the international research laboratory CERN, Geneva, Switzerland.

Stumpe built in 1972, following an idea launched by Frank Beck, a capacitive touchscreen[3][4][5][6] for controlling CERN's Super Proton Synchrotron accelerator.

[7][8][2][9][10] In 1973 Beck and Stumpe published a CERN report, outlining the concept for a prototype touchscreen as well as a multi-function computer-configurable knob.

[11][12] Bent Stumpe was educated within the Royal Danish Air Force and obtained a certificate as a radio/radar engineer in 1959.

[16] In combination with his activities at CERN, Stumpe was a consultant to the World Health Organization working on the development of an instrument for the early detection of Leprosy.
