John Dalton was born in Cumberland, England and served as a teacher and public speaker for a majority of his life. After teaching for ten years and moving to Manchester, Dalton joined the Manchester Literary and Philosophical Society. Here he read his first paper in public and began studying meteorology. Through his observations of the atmosphere, Dalton began studying gasses and the influence of heat on them, which eventually led to his Atomic Theory. Dalton’s atomic theory states that atoms cannot be created or destroyed, but merely altered.
