NOTABLE ALUMNI Founder Rowena Ravenclaw founded Ravenclaw House. She was known as a beautiful and intelligent witch, and her chocolate frog card calls her "the most brilliant witch of her time." Rowena valued learning, so she chose students who demonstrated cleverness and wisdom. Head of House Filius Flitwick is the Head of Ravenclaw House. He is the Charms professor at Hogwarts and the most knowledgeable Charms master alive today. According to the original Pottermore welcome letter, when Ravenclaws are extremely upset he makes little cupcakes do a dance to cheer them up. Ghost The Grey Lady also known as Helena Ravenclaw, is the Ravenclaw ghost. She rarely speaks to anyone outside Ravenclaw, but is a great resource for Ravenclaws who are lost or have lost something.
