Interesting to see all the answers. To put things in perspective, these were the languages I used at MIT from 1969-1975 (except for PL/1, we didn't have courses on programming per se, they just gave us the manuals and it was sink or swim):
Fortran -- Engineering classes
PL/1 -- Intro to Programming EE/CS
APL -- EE (network analysis, etc)
360 Assembler -- EE/CS systems course
PDP-8 Assembler -- EE/CS Project
PDP-9 Assembler -- EE/CS Project
Lisp -- EE/CS AI class and structure and theory of Programming languages
CLU -- EE/CS Research
Pascal -- grad school
I'm sure there were some others in there. I didn't really learn C until I started working on the Unix kernel after grad school.
