French composer, writer, broadcaster, engineer, musicologist and acoustician of the 20th century. His innovative work in both the sciences —particularly communications and acoustics— and the various arts of music, literature and radio presentation after the end of World War II, as well as his anti-nuclear activism and cultural criticism garnered him widespread recognition in his lifetime.

Amongst the vast range of works and projects he undertook, Schaeffer is most widely and currently recognized for his accomplishments in electronic and experimental music,[2] at the core of which stands his role as the chief developer of a unique and early form of avant-garde music known as musique concrète.[3] The genre emerged out of Europe from the utilization of newmusic technology developed in the post-Nazi Germany era, following the advance of electroacoustic and acousmatic music.

Schaeffer's writings (which include written and radio-narrated essays, biographies, short novels, a number of musical treatises and several plays)[1][3][4] are often oriented towards his development of the genre, as well as the theoretics and philosophy of music in general.[5]

Today, Schaeffer is considered one of the most influential experimental, electroacoustic and subsequently electronic musicians, having been the first composer to utilize a number of contemporary recording and sampling techniques that are now used worldwide by nearly all record production companies.[2] His collaborative endeavors are considered milestones in the histories ofelectronic and experimental music.
