Jared Diamond

Jared Diamond (born in Boston in 1937) is an American author whose work crosses biology, geography, anthropology and history. Trained first in biochemistry and physiology, he became known for building bridges between disciplines to explain why some societies thrive while others fail. His reach extends well beyond academia, although specialists have often challenged his conclusions.

Diamond was born to Ashkenazi Jewish immigrants from Eastern Europe. His father was a physician of Bessarabian Jewish origin, and his mother was a teacher, linguist and concert pianist. As a child he studied piano and, according to a well-known anecdote, later proposed to his wife after playing her Brahms's Intermezzo in A major. By the age of seven he had taken up birdwatching, a passion that led to published work in ornithology. He graduated from Harvard in 1958 and earned a PhD at Cambridge in 1961 with a thesis on the physiology of membranes in the gallbladder. He returned to Harvard, and in 1968 joined the physiology faculty at UCLA.

His career unfolded in overlapping stages: physiology, then ornithology and ecology, with fieldwork in New Guinea from 1964, and finally, in mid-career, environmental history. That range is why he is often described as a polymath. In his popular books he gathers evidence from anthropology, genetics, ecology and linguistics to answer very broad questions. His explanations rely on material factors such as climate, the availability of domesticable plants and animals, and the orientation of continents, though he insists that human choices also shape what happens to societies.

The Third Chimpanzee (1991) brought him a general readership, and Guns, Germs, and Steel (1997) became an international bestseller and won the 1998 Pulitzer Prize for general nonfiction. Collapse (2005) looked at past societies that vanished or struggled, among them the Maya and the people of Easter Island, while The World Until Yesterday (2012) compared the practices of traditional societies with those of the industrial world. His work has drawn sharp criticism from historians, anthropologists and geographers, who point to factual and logical errors and to oversimplified portrayals of specific cultures. Some of his ideas, especially the notion that tribal societies are static, remain heavily contested.

His legacy lies mainly in public debate. He popularised the idea that geography and ecology shape history, and many readers know him through his books and the television documentaries based on them. He retired from UCLA in 2024. His work serves both as an engaging starting point and as a case study in the limits of popular history.
