Potioneer

Potioneer is a title used for someone who makes potions, either as a profession or as an advanced student.

• The legendary potions-maker Zygmunt Budge calls himself a Potioneer, but also used the term for the students reading his Book of Potions (BoP). The term is used as both a job title and an honorary one, based more on skill than educational background (especially since Zygmunt Budge never graduated from Hogwarts).
• Professor Slughorn referred to Harry as a Potioneer because he was doing so well in class. What he never knew was that Harry was using the helpful notes in the Half-Blood Prince's potions book to get ahead (HBP18).
• Slughorn mentioned the Most Extraordinary Society of Potioneers founded by Hector Dagworth-Granger (no relation to Hermione) (HBP9).
• Severus Snape never referred to himself as a Potioneer, but as Potions Master of Hogwarts, which was his job title (CS9). However, since he brewed the Mandrake Restorative Draught during the Basilisk attacks, the Werewolf Potion for Remus Lupin, and Veritaserum for both Dumbledore and Umbridge, his range of potion-making went far beyond that of a mere teacher. For his youthful improvements in the Advanced Potion-Making book alone, he would probably be viewed as a Potioneer (HBP9,HBP12, HBP18).
• Dumbledore once had a paper published in the magazine "The Practical Potioneer" (DH2)

The following Witches and Wizards may qualify as Potioneers:
