Jared Diamond is an American scientist and author widely regarded as one of the most influential voices in popular science writing on human history and civilization. Born in Boston, Massachusetts, he trained originally as a physiologist before turning his research toward evolutionary biology, geography, and anthropology, rising to international acclaim with his Pulitzer Prize-winning book Guns, Germs, and Steel, followed by works including Collapse and The World Until Yesterday. A longtime professor of geography at UCLA, he draws on decades of fieldwork across New Guinea and the Pacific to explore why civilizations rise, flourish, and sometimes collapse, weaving together evidence from biology, ecology, and history into sweeping, big-picture narratives. Guns, Germs, and Steel became a global publishing phenomenon and was later adapted into a documentary series, bringing his theories on geography and the origins of inequality among societies to a massive popular audience. Known for his ambitious, interdisciplinary approach to explaining the trajectory of human civilizations, Diamond's work continues to shape modern popular science writing and inspire readers across the world.
