After a 53-year long career at Cornell spent shaping the field of computer science and its disciples, Prof. John Hopcroft delivered his final lecture to an empty lecture hall on April 29. It was not how he envisioned his last hurrah. “It’s fundamentally different to teach a hundred students when they’re physically there and you can interact with them, and when you’re giving a lecture to an empty hall and simply being videotaped,” Hopcroft said in an interview with The Sun. Hopcroft’s illustrious reign over computer science research and education began with his own teachers, who showed him what it meant to be a good educator. “[Throughout my education] there were a number of faculty who really cared about my learning, and my being successful,” Hopcroft said.
