When I switched from Political Science to Speech at the University of Oregon, Dr. Cohen was my second professor on that first day. He unveiled the fascinating area of rhetorical theory. With his pipe and tweed jacket, he fit the stereotypical image of a professor, which was reinforced by his level of knowledge, curiosity, and his interest in students. At that moment I knew nothing of his scholarship or professional activity--all I knew is this engagement with such a thoughtful person was why I was in graduate school. He was a model that few can ever reach. His leaving leaves an empty spot among the towering giants of the field.
