Michel Petrucciani

French jazz pianist. Petrucciani is from an Italo-French family (his grandfather was from Naples, Italy), and was known as one of the best jazz pianists of his time. He achieved this despite having the genetic disease OI (Osteogenesis Imperfecta, aka Brittle Bone Disease), a condition that causes brittle bones, in his case, short stature and near constant pain in his arms.
