Artie Nielsen (Saul Rubinek)Arthur Artie Nielsen is a Secret Service agent and the special agent in charge of Warehouse 13, a secret U.S. government repository in South Dakota where special artifacts with historical significance-- and imbued with supernatural powers-- are stored.Artie is boss to agents Myka Bering, Pete Lattimer, Claudia Donovan, and Steve Jinks. He answers to Mrs. Frederic and the Regents.Artie has worked as a Warehouse agent for over 30 years following stints as a codebreaker and cryptographer for the National Security Agency.Brilliant, cunning, and not above bending the rules Artie is a genius. There is perhaps no one in the world that knows as much about the artifacts housed in the Warehouse and still out in the world than Artie, whose own brain is something of a warehouse itself.Artie grew up in Philadelphia to a music teacher father and became an accomplished pianist himself, turning down admission to Juilliard to work for the NSA. His own busy mind, coupled with working in the remote Warehouse, has transformed Artie into something of an eccentric. He can be fussy and cranky, especially when dealing with the younger agents. He loves classical music and baking cookies. In addition to English, Artie is fluent in Russian, German and French.
