Lucien Lévy (11 March 1892 – 24 May 1965) was a French radio engineer and radio receiver manufacturer.
He invented the superheterodyne method of amplifying radio signals, used in almost all AM radio receivers.
His patent claim was at first disallowed in the United States in favour of the American Edwin Howard Armstrong, but on appeal Lévy's claim as inventor was accepted in the US.
Bertrand Goldschmidt (2 November 1912 – 11 June 2002) was a French chemist. He is considered one of the fathers of the French atomic bomb, which was tested for the first time in 1960 in the nuclear test Gerboise Bleue.
Paul Marie Alfred Lebeau (19 December 1868 – 18 November 1959) was a French chemist. He studied at the elite École supérieure de physique et de chimie industrielles de la ville de Paris (ESPCI). Together with his doctoral advisor Henri Moissan he was working on fluorine chemistry discovering several new compounds, like bromine trifluoride, oxygen difluoride, selenium tetrafluoride and sulfur hexafluoride.
In 1899 he was able to obtain pure beryllium by electrolysis sodium fluoroberyllate (Na2[BeF2]).
In World War I he improved the gas mask design used by the French army.
Georges Claude (24 September 1870 – 23 May 1960) was a French engineer and inventor. He is noted for his early work on the industrial liquefaction of air, for the invention and commercialization of neon lighting, and for a large experiment on generating energy by pumping cold seawater up from the depths. He has been considered by some to be "the Edison of France". Claude was an active collaborator with the German occupiers of France during the Second World War, for which he was imprisoned in 1945 and stripped of his honors.
