Xenakis was a Romanian-born French composer, architect, and mathematician. He started out studying engineering and music in Greece but was forced to flee in 1947 when he was denounced as a communist. He moved to Paris and, for the next 12 years, worked with the architect Le Corbusier. In his 30s, he began seriously studying composition with Olivier Messiaen and others and earned acclaim for his use of mathematical models in musical composition.
