I received this photo from Marshall, one of the MIT Alumni Hockey team members:
The gentlemen shown are, from left to right, Pete Gasparini (Goalie), Dr. Brian Fabes, and Mike Westphal. The photo was taken at the post-game celebration, to which Hubby and I have been courteously invited for next year.
As for the name “Beaver Cup,” its genesis is simple: both MIT and CalTech have chosen the beaver as their mascot. So, no matter which team wins, the cup is held by the Beavers.
