Donald Bitzer was the first Computer Science professor I had in college. He taught a discrete mathematics course (boolean logic).
Though he was on the older side when I took his course, he still brought laughter and enthusiasm to his classes, and set the tone for the rest of my college career. He will be missed!
Same. It was my first CS class after transferring to NCSU in 2000. I was pretty lost at times but he was super kind and patient whenever I went to office hours. He was an older professor at that time and it was always cool to see was still teaching well beyond when I graduated.
Ditto, I took his discrete math course at NCSU in 1998. It was mainly taught by Tiffany Barnes day to day (who was also nice and a great explainer), but Bitzer was often present and always smiling and jovial.
I really regret having spent so little time interacting with my professors though. I was one of those kids that spent the least amount of time in class possible, almost never going to office hours, aiming to get the course work out of the way asap so I could "have a life". So much wisdom and life/industry experience was concentrated on that campus and at my fingertips, but I totally took it for granted. Seeing his obit amplifies this feeling; I wish I had cared enough at the time to meet and know the guy.
Yeah, there were some other older professors at NC State who had clearly aged out of knowing the state of the art, but Bitzer was an enthusastic teacher who cared about engaging students, and still knew his stuff.
