Who became the first father and son to win the NHL's most valuable player award?

Question

In 1990, who became the first son and father to play on the same Major League Baseball team at the same time (the Seattle Mariners), and the only father and son pair to hit back to back home runs?

Answer 1

Bobby and Brett Hull.
Brett Hull of the St. Louis Blues became part of the first father-son team to win the Hart Trophy when he was named the NHL's most valuable player at the league's award ceremony.

Hull, son of Hall of Famer Bobby Hull, beat out scoring champion Wayne Gretzky of the Kings and Chicago rookie goaltender Ed Belfour, who won two other awards, in the balloting by selected members of the Professional Hockey Writers Assn.
