MIT’s longtime mascot, the Beaver, turns 100 on January 17, 2014, and everyone is invited. Since its arrival, the beaver—now known as Tim—has become a familiar face around campus, both in person and in print. To honor his centennial, check out a gallery of rare images that honors Tim and highlights how much the beaver has changed over past 100 years.
