His philosophy of teaching was a little puzzling. “My policy is to teach the student as much as possible and to require from him or her as little as possible,” he told Donald Albers and Gerald Alexanderson, the authors of “Mathematical People: Profiles and Interviews” in 2008. But, he added, the impact of his apparent lenience was that many of his students worked harder in his course than in any other. Would love to see more studies around this methodology and its impact on students. Not only an incredible professor, but an innovative teacher. Rest in peace!
