Who played Arthur "Fonzie" Fonzarelli on Happy Days?

Henry Winkler played Fonzie in every episode of Happy Days, making him one of two actors to appear in all 255 episodes (Tom Bosley is the other). He started out as a recurring character in the first season, but his popularity with viewers made him a member of the main cast for the remaining 10 seasons.
