Kurt von Hammerstein-Equord was a German field marshal who tried repeatedly to lure Hitler to visit bases under his command, where "a fatal accident will occur," and who referred to the Nazi party as "that gang of criminals." I found the following quote on Chip Morningstar's site. Heroes come from odder and odder places the older I get. At least they come.
"I divide my officers into four classes; the clever, the lazy, the industrious, and the stupid. Each officer possesses at least two of these qualities. Those who are clever and industrious are fitted for the highest staff appointments. Use can be made of those who are stupid and lazy. The man who is clever and lazy however is for the very highest command; he has the temperament and nerves to deal with all situations. But whoever is stupid and industrious is a menace and must be removed immediately."
