Aristotle developed early concepts of management such as specialization of labor and delegation of authority. In the 17th century, Hobbes advocated for autocratic leadership while Locke advocated for participatory management. Adam Smith's Wealth of Nations in 1776 revolutionized economic thought by suggesting centralization of labor and specialization in factories. The field of industrial/organizational psychology began emerging in the late 19th century with the founding of management schools and experiments applying psychology concepts to workplaces. Pioneers like Munsterberg, Scott, and Taylor made influential early contributions by applying findings from experimental psychology to practical workplace issues.
