What a wonderful tribute from family. It triggered a flood of good memories of what an original Bob truly was.
As one of his students in the late-70s, Bob had a profound impact on me as I struggled to find some direction and raise a badly damaged GPA after dropping out of NTSU. From logic to Nietzsche, afternoon "faculty consults" at Tolbert's Chili Parlor to amateur night at the Kowbell, this man was a caring, remarkable educator, and a kind and generous mentor.
I passed along one of his most useful lectures to my son when he entered university, which I summarize as: a subtle approach to BS'ing your instructor into giving you a higher grade. It worked in 1978, and in 2011.
Bob, wherever you are, I thank you from the bottom of my heart for all that you did, for me and so many others. You had an amazing run at life, eh?
