Aho taught the programming languages course at my Uni, and he loved to tell stories about Bell Labs, and this Brian guy in particular. ‘Let me tell you, I’d walk into Brian’s office and say, Brian, you really messed that language up...’ The entire semester I was like who the f is this Brian guy? Years later I was like oh shit, Brian is Brian Kernighan, and the language is C! And I realized I missed a freaking awesome opportunity to ask Al Aho about some serious heads in CS.
