Tech Reunions drew 3,324 alumni and guests to campus June 1–4 for MIT’s largest alumni gathering of the year—a multigenerational celebration of Brass Rats, red jackets, techy culture, and the joys of coming together as a community.

Events kicked off on Thursday, when the 50th reunion Class of 1973 led the traditional Commencement procession into Killian Court. Bedecked in their signature red jackets, these alums helped welcome 3,735 new graduates into the folds of the MIT Alumni Association, which now represents nearly 145,000 alumni worldwide.

MITAA president Steve Baker ’84, MArch ’88 served as the chief marshal for the Commencement exercises—MIT’s 118th—which included a keynote address from Mark Rober, a YouTuber, engineer, educator, and founder of CrunchLabs. 

President Sally Kornbluth conferred degrees for the first time and enjoyed her first Tech Reunions weekend—notably sharing her vision for the Institute during a fireside chat for alums on Saturday during a space-themed Technology Day. Overall, the festivities included more than 140 events, among them such favorites as Tech Night at Pops and Toast to Tech. 

Here are some highlights—by the numbers.
