Gilbert Stein (January 11, 1928 – March 24, 2022) was an American lawyer, law instructor, and professional ice hockey executive. Stein attended Temple University and studied law at Boston University. In 1982, he appeared before a United States Senate committee to discuss retransmission of television signals by cable operators.
After the owners disliked the way that Ziegler handled the 1991–92 NHL strike, they desired to abolish the position of president in favor of having a commissioner. He was appointed as interim president on June 22, 1992, and became full president on September 30. After taking over from Ziegler, Stein fired Brian O'Neill, the longtime overseer of league discipline, and took over the position himself. Stein then instituted a policy of suspending players on non-game days (such as practice) rather than games for violent actions. Stein also attempted to block O'Neill's Hall of Fame candidacy by removing him from the board of members for the Hall (O'Neil was later elected in 1994).
Stein also supported having NHL Players in the 1994 Winter Olympics as a way to grow NHL support in Europe. Two expansion teams came in the Mighty Ducks of Anaheim and Florida Panthers during his tenure. The announcement of the Panthers attracted the ire of Phil Esposito, president and general manager of the young Tampa Bay Lightning (who began play one year before Florida in 1992), as Stein initially told Esposito that no teams would be added until 1996, as the Lightning were supposed to have time to develop a fanbase in the state of Florida. Esposito criticized Stein for going after expansion fees without regard to the long-term implications of franchise stability. In 1993, Stein was awarded the Lester Patrick Trophy for outstanding service to hockey in the United States.
Stein was behind the Hall of Fame board while president, spearheading a change in the voting process by simple majority with no secret ballots. Stein was selected as the first member of this policy to the Hall of Fame, which attracted allegations that he manipulated his induction; the Board did not speak with either the Board of Governors (headed by Bruce McNall, a friend of Stein) or Bettman, and Stein ultimately resigned his nomination and from the League. In his later years, he lived in an assisted living community in Gladwyne, Pennsylvania. Stein died from heart disease on March 24, 2022, at the age of 94.
