Gabriel Germinet (1882-1969) and Pierre Cusy were early innovators in the art of radio in theory and practice. Germinet began as an engineer in fluid mechanics, and his work in radio began in 1922 with a proposal for a radio news service, a project which never got off the ground but paved the way for subsequent works for radio and for Germinet and Cusy’s Théâtre radiophonique: Mode nouveau d’expression artistique, of 1926 one of the earliest book-length investigations of radiophonic art. With Cusy, Germinet developed Radiola, the first private radio station in France, into a hub of experiment - station advisors included Paul Valéry and Maurice Ravel - and in 1924 the station became Radio-Paris. The station was nationalized by the French government in 1933. After the Battle of France in 1940 it was converted into a propaganda arm of the German invaders, transmitting until 1944 when it was liberated and then replaced by the new Radiodiffusion de la Nation Française.

Pierre Cusy’s biographical information is not known beyond his work for Radiola and Radio-Paris, though according to literary scholar Emilie Morin there are indications that this may have been a pseudonym for a printer named Pierre Giroud.
