Today's New York Times announced the death of social ecologist and management guru Peter Drucker at age 95.

Drucker's vision of business as a conduit to both profit and employment advocated the idea of the worker as a resource, not a cost and lead to a new era in management.

The story included some classic Drucker quotes, including:

"The only things that evolve by themselves in an organization are disorder, friction and malperformance."

While in some circles, he was more often right than popular, Drucker's observations and theories have guided progressive managers for decades and will live on for many more.
