Largely considered to be the most powerful wizard of his generation, who was the Hogwarts headmaster for almost 40 years?

Albus Percival Wulfric Brian Dumbledore: It's a big name for a big wizard. Professor Dumbledore was the Headmaster at Hogwarts during most of Harry's stay at the wizarding school. He serves as a mentor to Harry and aides him in his quest to take down Voldemort. Ultimately, he's killed by Snape at his own behest.
