I'm hoping this is a typo '191 years ago'. Don't mean to sound pedantic just interested when this was. My friend was in Caltech for his MS + PhD in Electrical engineering from 2008 onwards. I think he graduated in 2014-ish.

Not a typo, just an amusing ambiguity: the course was 191. It would have been around the same time as your friend.
