Georges Charpak (born Jerzy Charpak, 1 August 1924 – 29 September 2010) was a Polish born, French physicist from a Polish Jewish family.


In 1959, he joined the staff of CERN (European Organization for Nuclear Research) in Geneva. This is where he invented, and developed, the multiwire proportional chamber. The chamber was patented and that quickly superseded the old bubble chambers, allowing for better data processing.

Charpak was later to become a joint inventor with Ngoc and Policarpo of the scintillation drift chamber during the latter parts of the 1970s.

In 1980, Georges Charpak became professor-in-residence at École supérieure de physique et de chimie industrielles in Paris (ESPCI) and held the Joliot-Curie Chair there in 1984. This is where he developed and demonstrated the powerful applications of the particle detectors he invented, most notably for enabling better health diagnostics. He was the co-founder of a number of start-up in the biomedical arena, including Molecular Engines Laboratories, Biospace Instruments and SuperSonic Imagine – together with Mathias Fink. He was elected to the French Academy of Sciences on 20 May 1985.


Georges Charpak was awarded the Nobel Prize in Physics in 1992 "for his invention and development of particle detectors, in particular the multiwire proportional chamber", with affiliations to both École supérieure de physique et de chimie industrielles (ESPCI) and CERN. This was the last time a single person was awarded the physics prize, as of 2015.
