Ira Gitler, who was one of the most respected and prolific jazz writers of the postwar era and an early champion of bebop, died on Saturday in Manhattan. He was 90.
Mr. Gitler’s criticism appeared regularly in publications like DownBeat and JazzTimes. He wrote two books about bebop, the challenging form of modern jazz that emerged in the 1940s. And, along with Leonard Feather and Nat Hentoff, he was among the most prodigious writers of liner notes, annotating more than 700 albums.
