Well, there are Trelawney and Firenze, who will probably both teach 
Divination. But of course these are very special circumstances. But I 
never read it the way, that Dumbledore became Headmaster, just before 
Lupin arrived. I thought, Lupin said, that he was lucky, that 
Dumbledore was Headmaster, when he wanted to go to Hogwarts.
