 In 1942 French composer and theoretician Pierre Schaeffer began his exploration of radiophony when he joined Jacques Copeau and his pupils in the foundation of the Studio d'Essai de la Radiodiffusion nationale.The studio originally functioned as a center for the Resistance movement in French radio, which in August 1944 was responsible for the first broadcasts in liberated Paris.It was here that Schaeffer began to experiment with creative radiophonic techniques using the sound technologies of the time .
