Noted management writer and thinker Peter Drucker died last Friday aged 95. The world will be a poorer place without Drucker who virtually invented modern management theory in the 1930s.
What I most admire about him was that he represented the triumph of substance over appearance. Long after he became famous he remained at a small college where he could focus on his work, he was never interested in the received wisdom or popular theories but instead had his own deeply considered views on things and he was much more interested in understanding the daily grind of making a company efficient and profitable than the cult of leadership that infects modern business.
And of course he managed to stay active and engaged and continue to make an real contribution at an age when most of us are long gone (if not physically then at least mentally). A wonderful role model for anyone who believes in the importance of ideas and intellect.
