Polish-French physicist invented the multiwire proportional chamber an electronic detector for the development of subatomic particles, a breakthrough technique for exploring the innermost parts of matter. As particle physicists have focused their interest on very rare particle interactions, which often reveal the secrets of the inner parts of matter, sometimes only one particle interaction in a billion is the one searched for.

He was awarded the Nobel Prize for Physics in 1992

Charpak replaced now inadequate photographic methods with modern electronics that connected the detector directly to a computer.
