For rare-book collectors, an original copy of the Gutenberg Bible—of which there are fewer than 50 in existence (and which can sell for $100 million)—represents the ultimate prize. One copy, Number 45, passed through the hands of Johannes Gutenberg, monks, an earl, billionaires, bibliophiles, the Worcestershire sauce king, and a nuclear physicist before arriving at its ultimate resting place, in a steel vault in Tokyo. Estelle Doheny, the first woman collector to add the book to her library and its last private owner, tipped the Bible onto a trajectory that forever changed our understanding of the first mechanically printed book.

In today's episode I'm speaking with Margaret Leslie Davis, author of The Lost Gutenberg: The Astounding Story of One Book's Five-Hundred-Year Odyssey. She focuses on two protagonists in her story: the copy of the Gutenberg Bible itself and Doheny, a California heiress who emerged from scandal to chase it. We discussed the value we place on rare books, and the shifting wealth and power of those who hunt them.
