Feb. 15, 1991. In a short press conference, Chancellor Tien officially announced that beginning next semester, UC Berkeley would become co-ed. Men would be allowed to register for classes at Cal for the first time in the school’s history. After detailing the historic plan to reporters, the Chancellor abruptly stopped and said, “Wait a minute_I’m thinking of Mills. We’ve already got boys, haven’t we?” As the press conference came to a close, Tien declared that Fridays would now be “free dress” days, when students would not have to wear the school uniform to class.
