Looks like an ancestor of Robin Williams...
Mozart's youngest son was taught by Salieri after Mozart died, so I guess Mozart's widow didn't think that Salieri poisoned her husband.
I've loved the music of the other supremely talented composer who died young that was featured in the movie Amadeus. Pergolesi. In the movie Salieri listens to Pergolesi's music when he was sitting in church as a boy wishing he could compose music like that.
