<p>I read on one of these threads that Columbia didn't become coed until 1983. This seems sort of late; is this the time when most private East Coast colleges made the switch?</p>
<p>Columbia was the last Ivy, but most of the others didn't go co-ed until too much earlier than Columbia--the 60's or 70's, I think. Until then several had an affiliated women's college like Barnard or Radcliffe.</p>
