Wolfgang Amadeus Mozart (1756-1791). Austrian composer whose cognitive profile has been the subject of extensive posthumous assessment, with multiple researchers identifying recognizable features of both the autism spectrum and Tourette's syndrome (the documented behaviors include sudden uncontrolled vocal outbursts, repetitive physical movements, scatological humor in the letters, and the well-attested ability to compose entire works internally before transcribing them with almost no revision). Mozart's cognitive signature is the discovery specialty operating in a domain where the integration apparatus existed in unusual abundance for the era — the Esterházy and Habsburg courts, the publishing infrastructure, the network of opera houses and aristocratic patrons that turned compositions into performed and circulated works. The integration was good enough for Mozart to live (poorly) on his music, and good enough to preserve nearly his entire output. (Speculative diagnostic assessment; Mozart died in the eighteenth century. The behavioral record is what it is, and the contemporary clinical literature reads it consistently.)
