Claude CohenTannoudji is a French physicist and Nobel Laureate. He shared the 1997 Nobel Prize in Physics with Steven Chu and William Daniel Phillips for research in methods of laser cooling and trapping atoms. He is still an active researcher, working at the cole Normale Suprieure in Paris.
CohenTannoudji was born in Constantine, Algeria, to Algerian Jewish parents Abraham CohenTannoudji and Sarah Sebbah. When describing his origins CohenTannoudji said My family, originally from Tangier, settled in Tunisia and then in Algeria in the 16th century after having fled Spain during the Inquisition. In fact, our name, CohenTannoudji, means simply the Cohen family from Tangiers. The Algerian Jews obtained the French citizenship in 1870 after Algeria became a French colony in 1830.
