In 1883, a treasure hunter named Moses Wilhelm Shapira claimed he had found the world's oldest Bible scroll. But then his nemesis accused him of forging it, and Shapira died humiliated. Over a century later, journalist and San Francisco State professor Chanan Tigay crossed five continents over five years to find out the truth. Tigay joins us to talk about “The Lost Book of Moses: The Hunt for the World’s Oldest Bible" and about the surprising discovery he made on the fifth floor of the SFSU library.
