Today - Sunday, September 19th, we're celebrating the 31st birthday of Hermione Granger, the cleverest Muggle-born to attend Hogwarts. After completing her seventh year of Hogwarts studies, she progressed into the Ministry of Magic, in the Department for the Regulation and Control of Magical Creatures. Before transferring to the Department of Magical Law Enforcement, she greatly improved the treatment of House Elves, and later worked towards abolishing pro-pureblood laws. Let's not forget her personal life; she later married Ron Weasley and had two children, Hugo and Rose!

Happy Birthday Hermione!

Hermione is portrayed by Emma Watson in the Potter films, and you can celebrate her birthday at her Fanclub!
