Beaumont Marjoribanks (1742—1845) was a pioneer in Herbology, having collected and classified many magical plants. For this he was featured on a Chocolate Frog Card. He is credited with discovering the effects of Gillyweed, despite Elladora Ketteridge stumbling upon them about a hundred years prior. There was a bust of Marjoribanks on the History of Magic classroom, next to Cuthbert Binns's desk.
