19th century

Classical economists such as Adam Smith (1723 - 1790) and John Stuart Mill (1806 - 1873) provided a theoretical background to resource-allocation, production, and pricing issues. About the same time, innovators like Eli Whitney (1765 - 1825), James Watt (1736 - 1819), and Matthew Boulton (1728 - 1809) developed elements of technical production such as standardization, quality-control procedures, cost-accounting, interchangeability of parts, and work-planning. Many of these aspects of management existed in the pre-1861 slave-based sector of the US economy. That environment saw 4 million people, as the contemporary usages had it, "managed" in profitable quasi-mass production.
By the late 19th century, marginal economists Alfred Marshall (1842 - 1924), Léon Walras (1834 - 1910), and others introduced a new layer of complexity to the theoretical underpinnings of management. Joseph Wharton offered the first tertiary-level course in management in 1881.
