Ludwig von Mises was a famous Austrian economist and was one of the most notable philosophers of the 20th century. During the course of his long and fertile career, he developed a cohesive, inferential science of economics grounded on the central adage that human beings act purposively to accomplish preferred ends. Through his countless studies and research, he concluded that the only feasible economic policy for mankind was by means of ‘laissez-faire’. His writings were dominated by theories pertaining to epistemology, economics, history, politics and philosophy. He was the first scholar to identify that economics is part of a larger science in human action, a science that he termed ‘praxeology’. After he moved to the United States, he had a significant influence over the libertarian movement there. During his lifetime, he was part of a number of organizations including the ‘Liberty Fund’, the ‘Reason Foundation’, ‘The Independent Institute’, ‘Foundation for Economic Education’ and the ‘Cato Institute’. He went on to become one of the most prominent influences for personalities like Israel Kirzner, Ludwig Lachmann and Hans-Hermann Hoppe, who were all members of the ‘Austrian School’ of thought, much like Mises was.
