Pierre Benjamin Monteux (4 April 1875 – 1 July 1964) was a French (later American) conductor. After violin and viola studies, and a decade as an orchestral player and occasional conductor, he began to receive regular conducting engagements in 1907. He came to prominence when, for Sergei Diaghilev's Ballets Russes company between 1911 and 1914, he conducted the world premieres of Stravinsky's The Rite of Spring and other prominent works including Petrushka, Ravel's Daphnis et Chloé, and Debussy's Jeux. Thereafter he directed orchestras around the world for more than half a century.
From 1917 to 1919 Monteux was the principal conductor of the French repertoire at the Metropolitan Opera in New York. He led the Boston Symphony Orchestra (1919–24), Amsterdam Concertgebouw Orchestra (1924–34), Orchestre Symphonique de Paris (1929–38) and San Francisco Symphony (1936–52). In 1961, aged eighty-six, he accepted the chief conductorship of the London Symphony Orchestra, a post which he held until his death three years later. Although known for his performances of the French repertoire, his chief love was the music of German composers, above all Brahms. He disliked recording, finding it incompatible with spontaneity, but he nevertheless made a substantial number of records.
