I was so sad to hear that Mike Mahoney died. He was not just a brilliant, razor-sharp mind, he was also a lovely, well-rounded human being. He was an inspired teacher and kept up with an impressive body of literature in widely disparate fields. But he would get a real twinkle in his eye when he talked about his wife, children, and grandchildren. He didn’t shield that aspect of his life from his graduate students, and I always admired and appreciated that about him. My heartfelt condolences to his family, friends, and colleagues. He will be dearly missed.
