On 26 March 2025, we celebrate the centenary of the birth of composer and conductor Pierre Boulez. To mark the occasion, we present the key dates in the long career of the man who founded and directed IRCAM for 15 years.
1925
Birth of Pierre Boulez on March 26, 1925. From an early age, he took an interest in music.
1944
Boulez is admitted to Olivier Messiaen's harmony class at the Paris Conservatoire and wins his first prize in harmony the following year. From 1944 to 1948, he composed his first opuses, often for piano. These included Douze Notations, Trois Psalmodies and Première Sonate, followed by Sonatine for flute and piano and the first version of Visage nuptial for soprano, alto, and chamber orchestra, based on poems by René Char.

At this time, Boulez opened up to the world and, through his travels, forged relationships with the leading figures of the musical avant-garde such as Luciano Berio, Luigi Nono, and Igor Stravinsky and also met artists such as Jackson Pollock and Willem de Kooning. These experiences were to have a major influence on his work.

1960
In Pli selon pli, for soprano and orchestra, Boulez paid tribute to the poet Mallarmé. This work is considered to be the culmination and closing work of ‘the first Boulez', who up until 1960 revolutionized musical thinking, writing, and listening more than any composer of his generation. The 1960s saw the start of his international career, during which he conducted the greatest orchestras in Europe and the United States.
1963
His first publication was his monograph, Penser la musique aujourd'hui (Thinking about music today). At the same time, he gave numerous lectures at summer courses in Darmstadt, where, along with Karlheinz Stockhausen, Luciano Berio, György Ligeti, and Luigi Nono, he established himself as one of the leading figures of his generation.
