2025 MIT BRASS RAT

The Brass Rat is MIT’s version of a class ring. The tradition of the Brass Rat started in 1929 when the senior class president decided to design a ring that the Institute Committee would approve as the Standard Technology Ring. Many discussions then took place to decide what would be on the ring, but eventually the choices were narrowed down to a beaver or the Great Dome. However, the committee decided that since many other schools have buildings similar to our Great Dome, they would choose the beaver to grace our beautiful rings. Soon after, the class of 1930 received their rings and became the first class to be able to wear the Standard Technology Rings, lovingly referred to as Brass Rats.
