Ulf Samuelsson, Swedish-American ice hockey player and coach
Ulf Bo Samuelsson (born March 26, 1964) is a Swedish-American former professional ice hockey defenceman who currently serves as assistant coach of the Florida Panthers of the National Hockey League. He played several seasons in the NHL with the Hartford Whalers, Pittsburgh Penguins, New York Rangers, Detroit Red Wings, and Philadelphia Flyers. He was a two-time Stanley Cup champion as a member of the Penguins in 1991 and 1992 and is the first European-born player to have 2,000 career penalty minutes.

During his playing career, Samuelsson was viewed by NHL stars as "the most hated man in hockey"; he was described to the New York Times as "the lowest form of human being" and someone whose play is all about "trying to hurt you and knock you out of the game". He is also infamous for his knee-to-knee hit on Boston Bruins Cam Neely during the 1991 playoffs that was a contributing factor of Neely's early retirement five years later.
