   • 1915, Basil King, chapter 3, in The Side Of The Angels:

     Poor old fellow's a dunderhead. That's where it is in a nutshell. Never could make a living. […] Nice old chap as ever lived. Only impractical, dreamy. Gentle as a sheep—and no more capable of running that big, expensive plant than a motherly old ewe.

     Cheney & Company swooned over Mr. Chalabi because he was telling them what they wanted to hear. . . . A half-dozen dunderheads who thought they knew everything assumed they could control Mr. Chalabi and use him as the instrument of their utopian fantasies.
