It was founded in the mid 1700s, as KING'S COLLEGE, and the name wasn't changed until it moved to its present site, at the end of the 19th century.
Oh sure, it had some Marxist and then full blown Commies profs, in the 2th century, but though the presidents, after Ike ( that's would be President Eisenhower; deary ), became more and more "squishy", it wasn't really until the 1970s, that the profs became more and more heavily lefty.
Not only did I grow up knowing quite a few of the profs there ( and also had some profs, at the college I went to, who had graduated from there and/or did graduated work there. before they taught and not a one of them were lefties!), but also remember, very well, the Quonset Huts, that were put up, on the campus, for the returning G.I.s and their families, who went there, after WW II, on the G.I. Bill.
Just because you find something on line, doesn't make it so.
2th = 20th century
Madame excuses? What made room for those profs? Fish rot from the head. Your touchy condemnations speak volumes about what they come from rather than what they are pointed at.

columnbia and berkeley were the chief schools through which the Frankfurt school made their entrance into the USA.
the frankfurt school taught that western civilization needed to be destroyed from within in order to create a communist state. their methodology for doing so was critical theory. one of their acolites in secondary education for example was howard zinn.
the reason that communists and jihhadists marched together in the early days of the iraq war was that both wanted the destruction of western civilization. only communists wanted a communist state to replace it. the jihhadists wanted and islamic state to replace it.
this is the reason that columbia acceptd edward said when I was there. He was in favor of americas destruction as constituted as much as the communists in power. they didn’t quibble as to details of what came after.
I was at columbia when obama was there. his political views were shaped by his days at columbia.
