Was Dumblebore ever a student at Hogwarts?

I'm de-lurking for the first time and apologies if this has come up 
before but I've had a good search of the database and I can't find 
anything on the subject. I don't know if anything has come up yet in 
the books regarding Dumblebore as a student but presumably he must 
have attended Hogwarts as a boy, what are people's thoughts on which 
house he was in. Could he be an heir to one of the houses? Clever 
Ravenclaw or kindly Hufflepuff, he seems to have plently of the 
attributes of both.
