Helga Hufflepuff is a fictional character from the Harry Potter Universe
Helga Hufflepuff was one of the original four founders of Hogwarts. She was head and namesake of Hufflepuff House, deciding to take in 'all the rest' of the students after selection by the other three founders. She was good friends with Rowena Ravenclaw, and was apparently known for her 'dexterity at food-related Charms'.
According to her Wizard Card, written by J.K. Rowling, Hufflepuff was 'Loved for her charming ways'.
One of Hufflepuff's known artifacts was a small golden goblet, inscribed with her signature badger. It was passed down to her descendant Hepzibah Smith, who it was stolen from by Tom Riddle and used to create a Horcrux.
