Walter Isaacson offers unique insight into innovation and the character of innovators and what enables them to succeed.  He has chronicled historic steps forward in technology and the people who made them happen—most recently in his acclaimed new biography of Elon Musk. That is one of a series of extraordinary biographies—of Steve Jobs, Leonardo DaVinci, Albert Einstein, Benjamin Franklin and Nobel prize winner Jennifer Doudna. Walter shares his thoughts and what he’s learned in a wide-ranging conversation with Daniel Yergin. Formerly editor of Time Magazine and CEO of CNN, Walter is now professor of history at Tulane University and host of “Amanpour and Company” on PBS and CNN.
