This title seems to imply something pretty bad about MIT and gender diversity. This feels like a good argument for putting the date on older articles in square brackets rather than parens. Brackets are commonly used for editorializing quotes (which titles most often are on HN) and thus might be less confusing in cases like this.
As far as I can tell, MIT didn't have a CS department until 1975 (when it was added to the EE department to become EECS; the same year Irene Greif in the OP got her PhD).
Before the 70s, many schools considered CS as part of a Math degree or an EE degree.
Fun fact: The percentage of students in CS that are female is half of what it was in the mid 80s. All this hubbub is there to disguise the fact that as soon as comp sci stopped being necessary to do useful things with computers, women left in droves.
