Lou Lamoriello, American ice hockey player, coach, and manager

Louis P. Lamoriello (born October 21, 1942) is an American professional ice hockey executive who is the president of hockey operations and general manager for the New York Islanders of the National Hockey League (NHL). He is also the former general manager of both the New Jersey Devils and the Toronto Maple Leafs. Lamoriello's tenure as general manager of the New Jersey Devils from 1987 to 2015 was the third-longest by an NHL general manager with a single team, following those of Conn Smythe and Art Ross. Lamoriello resigned from New Jersey on May 4, 2015, and became the 16th general manager of the Maple Leafs on July 23 of the same year.

Under Lamoriello's management, the Devils, who had been barely competitive for their first five years in New Jersey, became one of the most successful teams in the NHL. The Devils made the Stanley Cup playoffs all but three times between 1988 and 2012, qualified for five Stanley Cup Finals (in 1995, 2000, 2001, 2003, and 2012) and won the Stanley Cup three times (in 1995, 2000, and 2003). Lamoriello also served as general manager for Team USA in the 1996 World Cup of Hockey, in which the U.S. won the gold medal, as well as for the 1998 Winter Olympics in Nagano. Lamoriello also played a key role in negotiating the settlement of the 2004–05 NHL lockout to resume play for the 2005–06 season.

In 2009, Lamoriello was inducted into the Hockey Hall of Fame in the builders category, while in 2012, Lamoriello was inducted into the United States Hockey Hall of Fame.
