Please answer the following question: What is the answer for the question: What is the last name of the person who directed orchestras around the world for more than half a century? from the following article ?  Pierre Benjamin Monteux (pronounced [pjɛʁ mɔ̃.tø]; 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. Monteux was well known as a teacher. In 1932 he began a conducting class in Paris, which he developed into a summer school that was later moved to his summer home in Les Baux in the south of France. After moving permanently to the US in 1942, and taking American citizenship, he founded a school for conductors and orchestral musicians in Hancock, Maine. Among his students in France and America who went on to international fame were Lorin Maazel, Igor Markevitch, Neville Marriner, Seiji Ozawa, André Previn  and David Zinman. The school in Hancock has continued since Monteux's death.
