The parents, of course, but they left this time and place when I was still a teenager.
Both grandmothers, the aunts, the uncles, the brothers and sisters.
My fifth-grade teacher.
An older couple in Lincoln, Nebraska, he a prominent corporate attorney and she a Republican National Committeewoman from Nebraska, who took a lost teenager under their wing; I knew them, and depended upon them, more than twice as long as I had known my own parents.
The president of a wholesale hardware company in Lincoln, a bank director, and one of the "Doolittle's Raiders" (in fact, the only one who 100% fulfilled his mission), who helped (motivated) a recalcitrant student get through college.
The late David Hunter of Lincoln, Nebraska, who stole millions because of his infatuation with a much-younger woman, and later put a revolver into his mouth and pulled the trigger; he was prominent, in fact a leader, in Democrat politics, and as mean and violent and crooked as Hell, but he was also the best boss I ever had.
Clare Boothe Luce, with whom I carried on a long chatty correspondence until she died.
All the speech therapists I had during my last two years before graduating from the University of Nebraska.
Two old old one-time country doctors, one from the Sandhills of Nebraska, the other from Minnesota.
Friends in high school and college and thereafter, but those were equals, really, not "mentors."
Anything that is good about myself comes from all the above; all that is bad about myself is my own damned fault, and I freely admit it.
