Erwin Stein (7 November 1885 – 19 July 1958) was an Austrian musician and writer, prominent as a pupil and friend of Schoenberg, with whom he studied between 1906 and 1910.
[3] Also in 1921 he arranged Anton Bruckner's Seventh Symphony for chamber ensemble, this time with Hanns Eisler and Karl Rankl.
[4] In 1924 it was Stein to whom Schoenberg entrusted the delicate as well as important task of writing the first article – Neue Formprinzipien ('New Formal Principles') – on the gradual evolution of what was soon to be explicitly formulated as 'twelve-tone technique'.
At Universal one of his tasks was to complete a vocal score of the unfinished third act of Alban Berg’s Lulu.
[6] He fled to London to escape the Nazis and worked for many years as an editor for the music publisher Boosey & Hawkes.
