I didn't do my undergrad at Stanford, but I'm here as a grad student, and I believe they use Java for the intro classes. They do teach Python and C eventually, but no Lisp AFAIK.
I did my undergrad at Georgetown, where nearly every class used C++ (or C, for classes in things like OS and security).
I did my undergrad at Stanford, and after taking two simple intro courses, we had the first real intro to paradigms course (CS107). In that course, three languages were used: C++ (for a data structures project), Java (for an OOP and Concurrency project), and Lisp (for a context-free grammar project). I don't know if the course is still taught this way, but I thought it was great.
There's a new CS107 this year (along with a few other classes; they just redid the undergrad curriculum). One of my friends is a 107 TA and he is actually sitting next to me right now. Apparently 107 no longer includes anything on Lisp. :(
Ah I probably do not know you then. I graduated in '04. Do you know Zico? He graduated in '05 and is a grad student at Stanford now I believe. We were in the same algorithms class.
I don't know him personally, but I know who he is; I think we met once when I was a freshman, and then he gave a lecture for one of my classes last quarter. Andrew Ng speaks highly of him.
