Professor Godric Gryffindor was a wizard of medieval times and one of the four founders of Hogwarts School of Witchcraft and Wizardry. He was good friends with Salazar Slytherin but opposed him when he later thought that they should not accept Muggle-born students at Hogwarts. It is unknown when he died. Gryffindor's birthplace became known as Godric's Hollow, in his honour. Godric Gryffindor's portrait still remains at Hogwarts.
