Tofty
From Hpwiki
Professor Tofty, first name unknown, is a member of the Wizarding Examinations Authority and tests Harry (and other students) in their O.W.L. exams.
Professor Tofty is described as looking to Harry Potter like "the very oldest and baldest examiner." He first tests Harry in his practical Charms exam. He recognizes him as "the famous Potter," but his "quavery old voice" seems to have a calming effect on Harry.
Tofty next examines Harry on his practical Defence Against the Dark Arts (which Harry earned an Outstanding on.) He tests Harry on counterjinxes and defensive spells and then asks Harry to produce a Patronus for a bonus point. He cries in delight when Harry produces a fully-formed stag patronus, clapping "his veined and knotted hands enthusiastically."
Tofty is next seen in the practical Astronomy examination. When Dolores Umbridge attempts to sack Rubeus Hagrid, he first attempts to maintain order during the exam. Witnessing the outrage, he finds himself shouting "Galloping gargoyles!" having completely forgotten the exam. Once the commotion is over, he feebly states "Um...five minutes to go, everybody..."
Tofty's last appearance in the History of Magic exam. He helps escort Harry out after he has the vision of Sirius and offers a cooling drink of water.
