Dudley Williams was pleased to join the faculty at NC State in 1963 as the new head of the physics department. He had previously worked at Ohio State.
Williams had high expectations for his students, and on this day in 1963, he let them know what would happen if they failed to meet his expectations.
If they fell asleep in his class, Williams warned, he would throw a piece of chalk directly at them, according to Historical State, an online archive maintained by NCSU Libraries.
Would that be considered a “chalk talk?”
