1850, 1900, and 1950?
I received The Harvard Book as a prize from the Harvard Alumni Association back in the day and I believe it was the first chapter that contains a description of student life in the 1600s. The visitor was not impressed, saying that the students were indolent and just lounged around all day, and the facilities were not very big.
You should pick up a copy of the book of you're interested in Harvard history. I'm not sure where my copy is, or I'd look up answers for you.
