A part-timer in Business who I know pretty well (her husband I play darts together) sent me a link yesterday. In some kind of mad dream she was searching professor salaries through the years - I don't know why. But she came across this regents letter from Stephen F. Austin University from 1970. Here's her note:
"Just so you know, Dr. John D. Witt (item #5) made as much teaching as an associate prof in 1970 as I will make this year. I'd research to see where he is now, but I couldn't bear the results."
