Identifying the "most influential" authors in the social sciences can be subjective and depends on the criteria used (e.g., citation impact, theoretical contributions, or societal influence). However, the following seven authors are widely regarded as foundational and highly influential across various disciplines within the social sciences:
- Karl Marx (1818–1883)
- Field: Sociology, Political Economy
-
Influence: Marx's theories on capitalism, class struggle, and historical materialism have profoundly shaped sociology, economics, political science, and critical theory. His works, such as The Communist Manifesto and Das Kapital, remain central to discussions of inequality and power.
-
Max Weber (1864–1920)
- Field: Sociology, Political Economy
-
Influence: Weber's work on the Protestant work ethic, bureaucracy, and social stratification has been foundational in sociology and organizational studies. His concept of Verstehen (interpretive understanding) remains a key methodological approach in the social sciences.
-
Émile Durkheim (1858–1917)
- Field: Sociology
-
Influence: Durkheim is considered one of the founding figures of sociology. His work on social integration, the division of labor, and the study of suicide (Le Suicide) established sociology as a distinct scientific discipline.
-
Sigmund Freud (1856–1939)
- Field: Psychology, Psychoanalysis
-
Influence: Freud's theories on the unconscious mind, psychoanalysis, and human behavior have had a lasting impact on psychology, psychiatry, and cultural studies. His work also influenced sociology and anthropology.
-
John Maynard Keynes (1883–1946)
- Field: Economics
-
Influence: Keynes revolutionized economic thought with his theories on government intervention and demand-side economics (The General Theory of Employment, Interest, and Money). His ideas shaped modern macroeconomics and public policy.
-
Michel Foucault (1926–1984)
- Field: Philosophy, Sociology, Cultural Studies
-
Influence: Foucault's work on power, knowledge, and institutions (Discipline and Punish, The History of Sexuality) has been highly influential in critical theory, sociology, and post-structuralism. His ideas continue to shape debates on governance, identity, and social control.
-
Adam Smith (1723–1790)
- Field: Economics, Political Economy
- Influence: Often called the "father of modern economics," Smith's The Wealth of Nations laid the groundwork for classical economics and free-market theories. His ideas on the division of labor and the "invisible hand" remain central to economic thought.
Honorable Mentions:
- Simone de Beauvoir (1908–1986) - Feminist theory (The Second Sex).
- W.E.B. Du Bois (1868–1963) - Sociology, race studies (The Souls of Black Folk).

These authors have shaped the theoretical and methodological foundations of the social sciences, and their works continue to inspire and challenge scholars today.
