Joseph Priestley

The biography follows an eighteenth-century minister and experimental chemist from childhood and academy training through his teaching and pastoral posts, drawing on autobiographical papers and correspondence. It recounts his theological development and controversial writings, his close ties with scientific societies and figures, and detailed accounts of his pneumatic chemistry experiments and innovations such as preparation of mineral and gaseous substances and early eudiometry. The narrative covers his involvement in intellectual circles, the violent attack on his home and library, ensuing decision to emigrate, and his final years in America, while assessing his methods, philosophical outlook, and influence as a practical experimentalist.
