Gil Stein (1992-1993)[edit]
On June 22, 1992, Stein was announced as the new president of the league and formally took the position, succeeding John Ziegler. Ziegler had been forced out by owners dissatisfied with his agreement with the NHLPA, that ended a ten-day strike initiated by Bob Goodenow.
As president, Stein greatly expanded the visibility of the president's office during his term, often seen at games and being frequently interviewed on air and in print. Among his early actions after becoming president was a shake-up of league officers, ousting several vice-presidents, including Brian O'Neill, who had been the league's disciplinarian under Ziegler. Stein personally took over responsibility for league discipline, making it mandatory that suspended players pay their fines. He also implemented a policy of suspending players from practices on non-game days, instead of having them miss games. He advocated the use of NHL players at the 1994 Winter Olympics, but ran into opposition on the issue from team owners.
The league hired an executive search firm to help find a new commissioner at the same time that Stein's appointment was announced. Before the end of 1992, NHL governors selected Gary Bettman to become the league's first commissioner, starting on February 1, 1993. Stein had been a finalist for the job, but bowed out to avoid an internecine battle, and threw his support to Bettman.
When Stein's term ended on July 1, 1993, the duties of the president were given to the commissioner, a position that remains to this day.
