The Joseph Priestley Collection
Priestley's considerable talents as an experimental chemist led him to make discoveries about the properties of gases that revolutionized the science. He was a theologian, a historian, a linguist, and a writer of learned tracts on education, politics, literary criticism, oratory, grammar, psychology, perspective, metaphysics, electricity, and optics. He was above all a Christian minister of the Enlightenment, and his religious dissent made him a seminal figure in the history of modern Unitarianism.
