Jared Mason Diamond (born September 10, 1937) is an American geographer, historian, ornithologist, and author best known for his popular science books The Third Chimpanzee (1991); Guns, Germs, and Steel (1997, awarded a Pulitzer Prize); Collapse (2005), The World Until Yesterday (2012), and Upheaval (2019). Originally trained in biochemistry and physiology, Diamond is known for drawing from a variety of fields, including anthropology, ecology, geography, and evolutionary biology. He is a professor of geography at UCLA.
In 2005, Diamond was ranked ninth on a poll by Prospect and Foreign Policy of the world's top 100 public intellectuals.
Diamond was born on September 10, 1937, in Boston, Massachusetts, United States. Both of his parents were from Ashkenazi Jewish families who had emigrated to the United States. His father, Louis Diamond, was a physician who emigrated from Chișinău, (present-day Moldova, then known as Bessarabia), and his mother, Flora (Kaplan), a teacher, linguist, and concert pianist. Diamond began studying piano at age six. Years later, he would propose to his wife after playing the Brahms Intermezzo in A major for her.
Already at the age of seven he developed an interest in bird-watching. This became one of his major life-passions and resulted in a number of works published in ornithology.
At the age of 15 for the first time his parents took him outside of the eastern U.S., to Montana, where they spent holidays at the Hirschy's family ranch on Big Hole River. In summer 1956, as a college student, he returned to the ranch to work. Later, impressed by the beauty of the state, he regularly spent his own family holidays there, and Montana and the Bitterroot Valley became one of the key examples in his book Collapse: How Societies Choose to Fail or Succeed
He attended the Roxbury Latin School and earned a Bachelor of Arts in Biochemical Sciences from Harvard College in 1958 and a PhD on the physiology and biophysics of membranes in the gall bladder from Trinity College, Cambridge in 1961.
