Hogwarts Professors are the teachers of Hogwarts School of Witchcraft and Wizardry. They teach a variety of magical subjects, including Transfiguration, Charms and Defense Against the Dark Arts. Each house is led by a different Hogwarts Professor. When Harry Potter first attends Hogwarts, the headteacher is Professor Dumbledore and the head of Gryffindor house is Professor McGonagall, who also teaches Transfiguration. Other professors include Professor Sprout the Herbology teacher, Madam Trelawney the Professor of Divination and Professor Binns, who teaches History of Magic. The Defense Against Dark Arts teaching post is seen as cursed; during Harry’s time at Hogwarts no teacher taking on the role lasts longer than a year.
