J.K. Rowling named Hufflepuff house after its founder, Helga Hufflepuff.
Hufflepuff is one of the four houses at Hogwarts School of Witchcraft and Wizardry. The house was founded by Helga Hufflepuff, one of the four medieval witches and wizards who established Hogwarts. In the books, Hufflepuff is especially associated with hard work, patience, loyalty, and fair play. Its emblem is a badger, and its traditional colors are yellow and black.
The other founders are Godric Gryffindor, Rowena Ravenclaw, and Salazar Slytherin. Each founder’s name supplies the name of a Hogwarts house, which can make the question sound like it refers to a separate character. Hufflepuff students include Cedric Diggory, Nymphadora Tonks, and Newt Scamander. The house is sometimes unfairly treated as less important by characters, but the books present loyalty and courage as major strengths.
