I recently read that management guru Peter Drucker passed away last Friday at 95. I first heard about Drucker while I was a management student in college, where I read several of his books. To me, Drucker's theories seem more grounded in practical usage for real-world scenarios than other great management theorists, such as Abraham Maslow. Fortunately for business leaders and students of business, Drucker was a prolific teacher and author so his theories and ideas will live on for future managers to learn from.
