History of the Brass Rat by Erick P. '17

with pictures of the bezel design from 1930 to today

The Brass Rat, the MIT class ring. MIT students get theirs sophomore year and wear the beaver “sitting” on them until graduation. At Commencement, the ring is flipped over so that the beaver is sitting on the world. Legend has it that it is the third most recognized ring in the world, after the Superbowl Ring and the Pope Ring.

The tradition began in the spring of 1929 when senior class president C. Brigham Allen brought together a member from each of the Classes of 1930, 1931, and 1932 to design a ring that the Institute Committee would approve as the Standard Technology Ring. They couldn’t decide whether to put the beaver or the Dome on the bezel of ring. The Committee looked to the original discussion over the mascot, calling upon the now-famous defense of the beaver by Lester Gardner, class of 1897.

We first thought of the kangaroo which, like Tech, goes forward in leaps and bounds. Then we considered the elephant. He is wise, patient, strong, hardworking, and, like all who graduate from Tech, has a good hide. But neither of these were American animals. We turned to Mr. Hornady’s book on the animals of North America and instantly chose the beaver. The beaver not only typifies the Tech [student], but his habits are peculiarly our own. The beaver is noted for his engineering, mechanical skills, and industry. His habits are nocturnal. He does his best work in the dark.

With that in mind, along with the fact that many other schools had buildings similar to our Great Dome, the Committee ultimately decided to honor our hard-working and industrious mascot on the ring, allowing the class of 1930 to proudly wear the first-ever Standard Technology Ring, lovingly referred to as the Brass Rat.

Since then, each class has appointed its own Ring Committee to uphold these time-honored traditions. The committee strives to design a ring that we, as students, can take pride in, and which will, upon graduation, unite us all as graduates of the Massachusetts Institute of Technology.

Serving on the 2017 Ring Committee, I spent a lot of time closely inspecting and growing a deep love for the uniqueness of each of the different Brass Rats. One of my favorite MIT Admissions blog posts is Matt McGann’s “A bevy of Beautiful brass Rat bezels“, published in 2006. After a quick history of the Brass Rat, Matt catalogs all of the bezels from ’01 to ’08. An updated version was published in 2008 that added the ’00, ’09, ’10 bezels. He then updated it again in 2009 with the addition of the ’11 Brass Rat, but not since. I’m updating his list here with the additions of the ’12-’17 bezels and older bezels going all the way back to the original Standard Technology Ring.
