Murray Rothbard: Murray Newton Rothbard ( ; March 2, 1926 – January 7, 1995) was an American economist, philosopher, political theorist, and historian.

Rothbard was the founder and leading theoretician of anarcho-capitalism, a staunch advocate of historical revisionism, and a central figure in the twentieth-century American libertarian movement.  He wrote over twenty books on political theory, revisionist history, economics, and other subjects.  Rothbard asserted that all services provided by the "monopoly system of the corporate state" could be provided more efficiently by the private sector and wrote that the state is "the organization of robbery systematized and writ large."  He called fractional-reserve banking a form of fraud and opposed central banking.  He categorically opposed all military, political, and economic interventionism in the affairs of other nations.  According to his protégé Hans-Hermann Hoppe, "There would be no anarcho-capitalist movement to speak of without Rothbard."
