Gellert Grindelwald

Gellert Grindelwald (1882/1883 – March 1998) was a pure-blood Dark wizard who was considered to be amongst the most powerful and notorious wizards of all time, his only known superiors being Albus Dumbledore and Lord Voldemort. A student at Durmstrang Institute, Grindelwald was expelled for twisted, dark experiments and near-fatal attacks on students. After leaving Durmstrang, he fostered a romantic relationship with a young Albus Dumbledore, making plans to find the Deathly Hallows and lead a Wizarding revolution to end the International Statute of Secrecy, and create a new wizard-led order that would dominate Muggles.
