Proust, Joseph Louis - he was Berthollet's opponent in scientific debates - Berthollet's salt - is used in the manufacture of matches - matchbox - Pyotr Korobkov (I really messed up with this clue, forgetting that we have a pyromaniac in the game, sorry...)
But overall, they were good clues. Challenging. I was digging in the wrong direction a bit.
