It wasn't on my curriculum, and I've only worked with one person who was remotely familiar with Lisp. I've worked with more people that know Haskell than Lisp (though that seems like an outlier, I would guess Lisp/Scheme is still more popular than Haskell). It's totally possible that I'm an outlier or that it's regional, but I haven't seen any indication that Lisp is commonly known.
