Otto Erich Deutsch

Otto Erich Deutsch (5 September 1883 – 23 November 1967) was an Austrian musicologist. He is known for compiling the first comprehensive catalogue of Franz Schubert's compositions, first published in 1951 in English, with a revised edition published in 1978 in German. It is from this catalogue that the ''D'' numbers used to identify Schubert's works derive. Provided by Wikipedia
