Joseph Priestley (1733-1804) was a chemist, theologian, political thinker, and writer. He is known for the discovery of oxygen, carbon monoxide, carbonation, and the invention of the timeline. After his home in England was burned in a riot, he left England for Northumberland, PA in 1794 where he lived the last ten years of his life. Modeled on an English gentleman’s estate, Joseph Priestley House was built on a site overlooking the Susquehanna River and includes Priestley’s laboratory.
