Albus Dumbledore defeated Grindelwald, a famous dark wizard, in 
1945.  What is the relation to the timeline in which Tom Riddle 
opened the Chamber of Secrets specifically and in which Tom Riddle 
was at Hogwarts in general?  Is their any relation (familial or 
otherwise) between Grindelwald and Tom Riddle/Voldemort?
