Lucien_Lévy

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.
