Arthur Weasley is the patriarch of the Weasleys, a family of wizards who are considered "blood traitors" by Death Eaters for their interest in the Muggle world. He is married to Molly Weasley, with whom he has seven children, including Ron, Harry's best friend. During his time at Hogwarts, Arthur belonged to the house of Gryffindor. Arthur is described as being tall and thin, and as having a receding hairline and horn-rimmed glasses. An affable, light-hearted man, he tends not to be the authority figure in the family; his wife Molly handles that area. Arthur works for the Ministry of Magic, initially in the Misuse of Muggle Artefacts Office. He is obsessed with learning about Muggle customs and inventions and owns a large collection of mostly Muggle used items. His department lacks funding, and his salary is only just able to provide for a vast family, leaving his family finances precarious.
