I was a grad student at Princeton several decades ago. While my degree was in religious studies, I audited one of Professor Mahoney’s undergraduate courses on the history of science and became friends with him. He was always willing to meet with me to discuss issues from the course. He was as kind as he was knowledgeable. I learned more from him than from any of my teachers in religion. I stayed in touch with him intermittently and was very sad to learn of his death. He was a decent, unassuming, and generous person.
