An Austrian Perspective on the History of Economic Thought is a work of economic history written by Murray N. Rothbard. Rothbard notes in the introduction that the book was originally conceived as a "standard Adam Smith-to-the-present moderately sized book"; however, in the process of writing it, Rothbard expanded the project into a multi-volume series, and expanded the scope of the project to include economists who preceded Smith. Only the first two volumes, Economic Thought Before Adam Smith and Classical Economics, were completed before Rothbard's death in 1995.
