Michel Petrucciani (French pronunciation: [miʃɛl petʁutʃani]; Italian: [petrutˈtʃaːni]; 28 December 1962 – 6 January 1999) was a French jazz pianist. From birth he had osteogenesis imperfecta, a genetic disease that causes brittle bones and, in his case, short stature. He became one of the most accomplished jazz pianists of his generation despite having pain in his arms.
