Unidentified Potions student

"I should point out, however, only once did a student manage to brew a potion of sufficient quality to claim this prize. Nevertheless, good luck to you all."

- Horace Slughorn

This Potions student was a student of Horace Slughorn's during his first tenure as Potions Master at Hogwarts (between c. 1920 and 1981). They were the first and only student before Harry Potter to brew a Draught of Living Death with sufficient quality to earn a small vial of Felix Felicis.
