Forty years ago, a young radical Columbia Law student named Gus Reichbach became the first student prominently disciplined by Columbia University for his participation in the blockades and protests in 1968.

He is now Justice Gustin L. Reichbach of the State Supreme Court in Brooklyn (in the news most recently for presiding over the DeVecchio trial).

He has traded in his rebel bell bottoms for dapper designer suits, and his flowing hair has started to gray. He was back at Columbia on Wednesday for events commemorating the 40th anniversary of the student protests. (More events are scheduled for this weekend.)
