He was tireless, honest, and smart, and getting smarter all the time as he made a strong team stronger. His subordinates responded well to his leadership, but he wanted more. He would encourage and recruit the hardheaded, iconoclastic, passionate original thinkers whom others would often dismiss as too much trouble. They not only followed him, they challenged him to be better. They pushed him. They questioned him. They constructively, fearlessly voiced dissent if warranted. He did the same with me. That’s a mark of superlative subordinates; they make their bosses better leaders.
