1912-1988. Born Ian Ernest Gilmore Green, in Toronto. A bad pianist, but he used the piano to write arrangements that were inventive and second-to-none; had he been born a generation later, he might have been a Brian Wilson. The unwitting midwife of cool jazz, via his Birth of the Cool collaborations with Miles Davis, the first of many. In later years, his big band was perhaps the first to use Jimi Hendrix's music in a jazz context; the band continues, led by his trumpeter son Miles.
