From the bestselling author of How We Got To Now, The Ghost Map and Farsighted, a new national bestseller: the “exhilarating”( Los Angeles Times) story of Joseph Priestley, “a founding father long forgotten”(Newsweek) and a brilliant man who embodied the relationship between science, religion, and politics for America's Founding Fathers. In The Invention of Air, 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 uses of oxygen, scientific experimentation, 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: innovative strategies, intellectual models, and the way new ideas emerge and spread, and the environments that foster these breakthroughs.
