When Joseph Priestley (1733-1804) is remembered today, it’s usually for his 1774 discovery, in England, of oxygen. Few know he was a noted theologian, political progressive, and prolific author whose scientific contributions include the development of the modern timeline, the carbonation process, the identification of carbon monoxide and other gases, early experiments in electricity and an early understanding of the inter-relationship of plants and animals mediated by gases: oxygen and carbon dioxide and the role of sunlight in photosynthesis.
He counted Benjamin Franklin, Thomas Jefferson, and James Watt among his friends. Yet Priestley was also a controversial figure whose views were so odious to some of his countrymen that his house, Fair Hill in Birmingham, was burned in a riot in 1791, and he and his family fled to London and then left England in 1794. Priestley spent the last ten years of his life in Northumberland, Pennsylvania, where he continued his work in science, religion, and education. But even in this democratic republic his liberal ideas were frequently received with intolerance, and the peace that he so ardently desired was often elusive.
Joseph Priestley House and laboratory is an historic site that preserves and interprets the contributions and significance to American history of Joseph Priestley. As a National Historic Landmark and National Historic Chemical Landmark, the site features Priestley’s manor house with its laboratory. In the nearby Pond Building can be found the Joseph Priestley Timeline, a series of panels that present accomplishments during different periods of his life.
