How John Dalton's meteorological studies led to the discovery of atoms

In this episode of "Profiles in Chemistry," Arnold Thackray, founder of the Chemical Heritage Foundation (CHF), describes how a plainspoken schoolmaster named John Dalton published the seminal book on meteorology, which later led to his discovery of the nature of atoms. Thackray shows these books and some of Dalton's personal letters from the Sidney M. Edelstein Rare Book Room at CHF's Donald F. and Mildred Topp Othmer Library of Chemical History.
