Join Dr. Keith Devlin, “The Math Guy” from NPR’s *Weekend Edition*, as he recounts his exploration of the life and legacy of thirteenth century mathematician Leonardo of Pisa, popularly known as Fibonacci. Leonardo introduced the Hindu-Arabic numeral system and arithmetic to the Western world, and thereby helped start a global, social, and economic revolution. Devlin first shared Leonardo's story in a 2011 book titled *The Man of Numbers: Fibonacci’s Arithmetic Revolution*. His new book, *Finding Fibonacci*, describes his own experiences, reconstructed from his project diary and notes, together with the stories of three other contemporary scholars, each of whom investigated this long-forgotten medieval mathematician who did so much to create the world in which we live.
