|Name Jack Diether|
Jack Diether (1919–87) was a Canadian-born American music critic and musicologist prominent in the 1960s and '70s. He was best known for his expertise in and promotion of the music of Gustav Mahler and Anton Bruckner at a time when neither composer enjoyed wide critical acceptance.
It was Diether who in 1943 attempted unsuccessfully (by letter) to interest Dmitri Shostakovich in the task of producing a performable score from the draft of Mahler's unfinished Tenth Symphony; he was also present at a 1949 meeting between Alma Mahler and Arnold Schoenberg at which the latter declined to take on the same task.
The final issue of the journal Chord and Discord was dedicated to his memory.
The Jack Diether papers, dating from 1941 to 2006, are now held by the New York Public Library.
