Pierre Henri Marie Schaeffer (August 14, 1910–August 19, 1995) was a French composer, noted as the inventor of musique concrète. He is generally acknowledged as being the first composer to make music using magnetic tape. Schaeffer was born in Nancy. His parents were both engineers, and at first it seemed that Pierre would also take this as a career. He studied at the École Polytechnique and after a stint as a telecommunications engineer in Strasbourg from 1934, he found a job in 1936 at Radiodiffusion Française (RDF) in Paris.
