Professor Albus Dumbledore is the Headmaster of the school, but he also has numerous other responsibilities. He is described as a genius with an eccentric personality. He has a long white beard and half-moon-shaped glasses.
He is wise, calm, and powerful, and treats people with gentle humor and unfailing kindness. Dumbledore is perhaps the most respected wizard of all time. He often seems to have the solution to all the problems due to his immense knowledge of witchcraft. Although he is in charge of the school, he sometimes gives Harry implicit encouragement to break the rules to find the answers he is looking for.
Yet, Albus Dumbledore is a very secretive person. He has had many tragedies in his life that he keeps to himself and never reveals to anyone.
