Georges Charpak. Portrait of Georges Charpak (1924-2010), French physicist. Charpak was born in Poland, but in 1946 became a French citizen. He gained his doctorate at Paris in 1955, and in 1959 joined the CERN particle physics laboratory near Geneva. In the course of his research, Charpak became involved in the development of new types of particle detector. In 1968, he invented the multiwire proportional counter and the drift chamber. These allowed large detectors to operate quickly and be built cheaply. In the following years he stayed at the forefront of detector design. Charpak won the 1992 Nobel Prize for Physics. Photographed in 1994.
