Hogwarts professor of Herbology when Dumbledore was a young Transfiguration teacher (so in the first half of the 20th century). He directed the one and only Hogwarts Christmas pantomime, based on "The Fountain of Fair Fortune". It was a complete disaster. After leaving Hogwarts, he taught at the Wizarding Academy of the Dramatic Arts, but he never again produced a play based on that particular story.
