Alums

100 Years and Counting

tΞp was founded in 1917, and moved in to our current house in 1958. We have a very active Alumni community which can be found at AlumXi.com

Events

In non-pandemic times alums host many events, ranging from informal “Squids” get togethers, to Power Dinners whenever one of us happens to be visiting a city where a bunch of us live, to the annual Alumni Retreat in New England. During the pandemic, we’ve kept in touch with events like tΞp Talks and Story Hours, where we talk about things like measuring gravity waves and catching rockets on barges and share events in our lives.
