I had him as a teacher for my 2nd CS class in 1976, I think it was data structures using Pascal. I don't think I had another class which we laughed so much. Enough learning and fun that I considered switching my major from EE. And then he left to be part of the project that became Ada. It was still a good class, but it became a normal class. I stayed with EE. Thank you, Prof. Wulf, for that glimpse of something bigger. It stayed with me.
