I had Greenway for at least two anthro classes in early 60 thru mid 70s in Boulder, Colorado. Of all my teachers and profs he is the only one I still remember, and love. "Brilliant" isn't superlative enough to describe him. While I was myself a leftie at the time, I still found him fascinating, and he planted seeds in my mushy brain that sprouted years later. I will never forgive the PC police at Boulder for what they did to him.
