I only know he was a non-noble actor-playwright at the court of Louis XIV., which makes me assume the same thing. :) Checking on his German wiki entry, I see it also claims Alceste in The Misanthrope is the most autobiogrophical of his characters.

(Also, another thing he had in common with Voltaire was that since he was an actor who got in trouble with the church a couple of times (notoriously, because of Tartuffe, the play in which he makes fun of a religious hypocrites), he nearly hadn't gotten a Christian burial; it needed the personal intervention of Louis XIV. for it to happen.
