Composer
Iannis Xenakis (1922–2001), composer. As an illegal immigrant in Paris, Xenakis began working as a draftsman in 1947, and soon after as an architect in the office of Le Corbusier, while simultaneously composing. In the course of his work he developed ideas for a reciprocal transferability of architectural and musical forms, which he expanded into a mathematically based concept of structural equivalence. In 1977 he developed UPIC (Unité Polyagogique Informatique CEMAMu), a computer for sound synthesis with a graphical interface, which allowed the mechanical translation of drawings into sound. Xenakis is among the most important composers of the second half of the 20th century with instrumental as well as electroacoustic compositions. Xenakis: Musique formelle (1963); English: Formalized Music (1971, 1992).
