The bulk of these are Political Science and History professors with the exception of Vedder in Economics and Lawson in German. They cross the political spectrum but they taught me a great deal, even if I didn't always agree with their viewpoints.
Special Mention to Paul Milazzo of the History Department who came after I left my undergrad and grad days, but I have taken some of his summer classes and he's as good as they get.
Richard Bald would probably have made my list, except the class I took from him was during my "sophomore slump" where one semester I earned a 1.0 GPA. So, the fact that I didn't get what should have out of his class was not his fault but mine.
There are two things, though, that I will never forget about his class:
1. The day of the JFK assassination I heard about the shooting on my way to his class. At that point we did not know how seriously the president had been wounded. As we sat in the class a student in back row kept his transistor radio earphone in his ear. After about 35 minutes, he raised his hand, and announced to the class that, "The president is dead." The class was dismissed and we all wandered out of Bentley Hall in a collective daze. As I left the classroom, I glanced over at Professor Bald who looked perplexed and very profoundly sad, with a look in his eye that told me he was remembering the days of political upheaval in his native Germany.
2. In one of his lectures he was discussing the WWII Era (don't remember the exact topic of the lecture) and he broke into tears as he recalled an assignment his troop of Hitler Youth was given at one point late in war -- burying some bodies. I'm not sure his age at that time of this incident, but I think he was 8 or 9 years old. It was obviously a very searing and painful memory that he probably had not intended to mention, but somehow it came out. He quickly regain his composure and completed his lecture.
