Peter F. Drucker was a renowned management consultant and author born in Austria in 1909. He made numerous seminal contributions to the field of management through his writings and consulting work. Some of his most influential ideas included decentralization, treating workers as assets, and viewing corporations as human communities rather than just profit-making machines. His theories on knowledge workers, non-profits, marketing, and strategic planning remain highly relevant today. Drucker was considered a visionary for introducing many concepts decades before they became widely accepted.
