from Adam Kimelman of NHL.com,

There were owners of the six original NHL franchises and League president Clarence Campbell on one side of the table. On the other side were owners from the NFL, famous entertainers and politicians. On the agenda was the matter of League expansion, and 50 years ago Tuesday it all came together in what was a momentous day in the history of the NHL.

On Feb. 9, 1966, the League doubled in size with the birth of the "Second Six," the Board of Governors awarding franchises to Philadelphia, Los Angeles, Pittsburgh, San Francisco, Minneapolis-St. Paul and St. Louis.

From Feb. 7-9, 1966, Campbell gathered the Board of Governors at the St. Regis hotel in Manhattan for three days of meetings that would feature plenty of intrigue. Among those present were Charles Adams of the Boston Bruins, James Norris of the Chicago Blackhawks, Bruce Norris of the Detroit Red Wings, David Molson of the Montreal Canadiens, William Jennings of the New York Rangers and Conn Smythe of the Toronto Maple Leafs.

The most significant topic on the agenda was League expansion.
