From the author of The Ghost Map and Everything Bad Is Good for You , a new national bestseller: the "exhilarating"( Los Angeles Times ) story of "a founding father long forgotten."( Newsweek )

National bestselling author Steven Johnson tells the fascinating story of Joseph Priestley-scientist and theologian, protégé of Benjamin Franklin, friend of Thomas Jefferson-an eighteenth-century radical thinker who played pivotal roles in the invention of ecosystem science, the discovery of oxygen, the founding of the Unitarian Church, and the intellectual development of the United States. As he did so masterfully in The Ghost Map , Steven Johnson uses a dramatic historical story to explore themes that have long engaged him: innovation and the way new ideas emerge and spread, and the environments that foster these breakthroughs.
