Toots Thielemans, Belgian guitarist and harmonica player (died 2016)

Jean-Baptiste Frédéric Isidor, Baron Thielemans, known professionally as Toots Thielemans, was a Belgian jazz musician. He was mostly known for playing the chromatic harmonica, as well as his guitar and whistling skills, and composing. According to jazz historian Ted Gioia, his most important contribution was in "championing the humble harmonica", which Thielemans made into a "legitimate voice in jazz". He eventually became the "preeminent" jazz harmonica player.
