Peter Ferdinand Drucker (November 19, 1909 - November 11, 2005) was a writer, management consultant and university professor. His writing focused on management-related literature. Peter Drucker made famous the term knowledge worker and is thought to have unknowingly ushered in the knowledge economy, which effectively challenges Karl Marx's world-view of the political economy. George Orwell credits Peter Drucker as one of the few writers who predicted the German-Soviet Pact of 1939.
