Murray N. Rothbard was one of the founders of the modern libertarian movement and of the Libertarian Party.

Rothbard's Libertarian Manifesto was one of three books defining early libertarian philosophy, the other two being Nozick's Anarchy, State and Utopia and Hospers' Libertarianism.

Rothbard was S.J. Hall Distinguished Professor of Economics at the University of Nevada, Las Vegas, and Vice President for Academic Affairs of the Ludwig von Mises Institute in Auburn, Alabama.
