Granz is now the subject of a much-needed biography by Tad Hershorn called "Norman Granz: The Man Who Used Jazz for Justice" (University of California Press).
Carnegie was outbid on a limited-edition series of jazz recordings signed by impresario NormanGranz and outbid twice on a flier heralding a lecture on spiritualism by Arthur Conan Doyle.
Nowadays the name of NormanGranz, who died in 2001, is known only to gray-headed jazz buffs, but there's a fair chance that you own at least one of the hundreds of albums that he produced for Verve, the record label that he founded in 1956.
