One anecdote about him reminded me of a top, winning football coach.
His subordinates knew that he demanded top intellectual performance from them and he had zero tolerance for slacking off. But they also knew that if they did well in his team, their future was assured.
However, he was believed to have an IQ of 160-170, and a superb memory, and would frequently quiz his subordinates to make sure they were on the ball. So they had to spend their free time hitting the books.
One story of this was when he called a general into his office for such a snap quiz. “How many Iraqi generals are defending the southern border of Iraq?”
“42, sir,” the general replied, pleased that it was such an easy question.
“And what are their names?”, said General Schwarzkopf.
Very funny story!
RIP to a hero.
