What did Albus Dumbledore do after he graduated Hogwarts? Well first i have to get on fact straight...he taught Tom Riddle (who later on becomes Lord Voldemort) I know! He is seen talking to him in the film, Harry Potter and The Sorcerer's Stone (also know as Harry Potter and The Philosopher's Stone.) Tom at the time was a teen and a Prefect.

Albus taught Transfiguration before becoming Headmaster of Hogwarts. It is said that he became a master at Transfiguration, that's why he taught it.

Before we move on though, something very tragic happened over one summer that ended up scaring two brothers and a friend, and took the life of their sister. Learn more about that in the next chapter.
