The Invention of Air

Steven Johnson traces the life of Joseph Priestley, a figure who straddled the worlds of eighteenth-century chemistry, religious dissent, and political radicalism. While Priestley is best known for his discovery of oxygen, Johnson argues that this scientific breakthrough was inseparable from his broader intellectual project: a commitment to empirical observation and rational inquiry that challenged the established hierarchies of his time. The narrative follows Priestley from his early days as a nonconformist minister in England to his controversial experiments in Wiltshire and his eventual exile to the United States, where he continued to advocate for religious tolerance and political reform.

The book positions Priestley not merely as a chemist but as a central actor in the intellectual ferment that led to the American and French Revolutions. Johnson’s prose is accessible and narrative-driven, weaving together the details of laboratory work with the broader social and political upheavals of the era. By highlighting the connections between scientific discovery and social change, the work offers a nuanced portrait of a man whose life was defined by the tension between innovation and the conservative structures he sought to dismantle.
