Gustave Le Bon: The Almost Unknown Father of Crowd Psychology

Gustave Le Bon (1841–1931) was a French anthropologist, psychologist, and sociologist who pioneered the study of crowd psychology. Born in Nogent-le-Rotrou and dying in Marnes-la-Coquette, he scientifically analyzed crowd behavior during the rise of industrialization and urbanization, coining concepts like contagion and suggestion to explain how emotions emerge from instinct and the unconscious. His major work, "Psychologie des Foules" (1895), was studied by Hitler, Lenin, Stalin, Mussolini, and Theodore Roosevelt. Mussolini called it a capital work he often revisited. Le Bon also dabbled in physics with a rejected theory of luminiferous ether and invented a pocket cephalometer for craniometry, reflecting a frenological bent. Despite these eccentricities, his crowd psychology remains relevant in the age of social media and mass gatherings.
