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]

Education

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

Career

Leaving the Air Force, Stumpe was employed from 1959–1961 at the Danish radio and television factory TO-R Radio before he was employed by CERN from 1961 until 2003.^[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.^[16][17][18]
