Roy Rosenzweig died last night. I knew he was sick, but being removed from campus, I did not realize how sick he really was. I was working with him individually for a class this semester, and we exchanged emails only a week ago. These things happen so fast sometimes.

I may post some details of his career later, and how his work has shaped mine, but for now, my thoughts are with his family and the other GMU students and faculty who were working with him closely.
