At West Virginia State College, Johnson became immersed in academia and the mathematics program. She loved being surrounded by smart people, she said, and knew all of the professors and students on campus. One of her professors, the renowned Dr. William W. Schiefflin Claytor, recognized the bright and inquisitive mind that Johnson had. “You’d make a great research mathematician,” he told her. Then professor Claytor did something else. He told Johnson that he would help her become one. Johnson said, “Many professors tell you that you’d be good at this or that, but they don’t always help you with that career path. Professor Claytor made sure I was prepared to be a research mathematician.” He saw that Johnson took all of the mathematics classes listed in the catalog that were needed to pursue her life’s passion, and even went so far as to create a class in analytic geometry of space just for her. At age 18, Johnson graduated summa cum laude with Bachelor of Science degrees in mathematics and French. Johnson recalls of her professor, “Claytor was a young professor himself, and he would walk into the room, put his hand in his pocket, and take some chalk out, and continue yesterday’s lesson. But sometimes I could see that others in the class did not understand what he was teaching. So I would ask questions to help them. He’d tell me that I should know the answer, and I finally had to tell him that I did know the answer, but the other students did not. I could tell.”
