Yuval Noah Harari (Hebrew: ×××× × × ××¨×¨×ââ; born 24 February 1976) is an Israeli historian, tenured professor at the Department of History of the Hebrew University of Jerusalem and the author of the international bestseller Sapiens: A Brief History of Humankind.
In his book, Sapiens: A Brief History of Humankind, scientist Yuval Noah Harari attempts a seemingly impossible task â packing the entirety of human history into 400 pages. Harari, an Israeli historian, is interested in tackling big-picture questions and puncturing some of our dearly held beliefs about human progress. In some areas we've done amazingly well; in other areas we've done amazingly bad, he tells NPR's Arun Rath. The book charts humankind's journey from hunter-gatherer origins to a vision of the superhumans of the future.
