Anton von Webern, Austrian composer, 1883-1945

Along with his mentor Arnold Schoenberg and his colleague Alban Berg, Webern comprised the core among those within and more peripheral to the circle of the Second Viennese School, including Ernst Křenek and Theodor Adorno. As an exponent of atonality and twelve-tone technique, Webern exerted influence on contemporaries Luigi Dallapiccola, Křenek, and even Schoenberg himself. His music was the most radical of its milieu in its rigorous and resolute apprehension of twelve-tone technique.
