“Carl Philipp Gottlieb von Clausewitz (pronounced /ˈklaʊzəvɪts/; July 1, 1780[1] – November 16, 1831) was a Prussian soldier, military historian and military theorist. He is most famous for his military treatise Vom Kriege, translated into English as On War.

Vom Kriege (On War) is a long and intricate investigation of Clausewitz’s observations based on his own experience in the Wars of the French Revolution and the Napoleonic Wars and on considerable historical research into those wars and others. It is shaped not only by purely military and political considerations but by Clausewitz’s strong interests in art, science, and education.” (Description obtained from Wikipedia)
