Nuh-uh. Vikings were famous for bathing weekly - which some Europeans considered too often. They also took advantage of the natural Scandinavian hot springs, and even made soap out of CONKERS (horse chestnuts).
Halfdan Ragnarsson was a Viking leader and a commander of the Great Heathen Army. According to the tradition recorded in the Norse sagas he was one of the sons of Ragnar Lodbrok, and his brothers included Björn Ironside, Ivar the Boneless, Sigurd Snake-in-the-Eye and Ubba. He was the first King of Jórvík and also claimed the Kingdom of Dublin. He died at the Battle of Strangford Lough in 877 trying to press his Irish claim.
