Arthur Weasley

Arthur Weasley (born February 6, c. 1940s) is a fictional character in the Harry Potter series. He is the patriarch of the Weasley family and married to Molly Weasley with whom he has seven children: Bill, Charlie, Percy, Fred, George, Ron, and Ginny.

Arthur Weasley works for the Ministry of Magic, previously in the Misuse of Muggle Artifacts department (books 1-5), but was promoted to the head of Detection and Confiscation of Counterfeit Defensive Spells and Protective Objects in the 6th book. He is obsessed with learning about Muggle customs and inventions. He has been consistently against Lord Voldemort.

Arthur Weasley's youngest son Ron is one of Harry Potter's best friends. Harry and his other best friend Hermione Granger enjoy spending time with the Weasley family and they seem to have been accepted as unofficial members of it.

Harry Potter and the Order of the Phoenix, Mr. Weasley is a member of the Order of the Phoenix and is attacked by a snake being controlled by Voldemort. Harry, who is mentally connected with Voldemort, manages to see this in a dream and is able to warn the Hogwarts authorities and Mr. Weasley is saved just in time and sent to St Mungo's Hospital for Magical Maladies and Injuries.

The name Arthur Weasley is reminiscent of the birth name of Arthur Wesley, better known in later life as Arthur Wellesley, 1st Duke of Wellington, though at this point in the story it is difficult to know if he will be a similarly heroic figure. See Arthur for more information on other possible origins of Arthur Weasley's first name.

A favourite fan theory had been that Arthur Weasley might become the next Minister of Magic; however this hypothesis was denied by J. K. Rowling in her official website.
