Early life
John Dalton was born on 5 or 6 September 1766 into a Quaker family in Eaglesfield, near Cockermouth, in Cumberland, England.[3][4] His father was a weaver.[5] He received his early education from his father and from Quaker John Fletcher, who ran a private school in the nearby village of Pardshaw Hall.

Theories of Atomism and the Law of Partial Pressures
Dalton arrived at his view of atomism by way of meteorology, in which he was seriously interested for a long period: he kept daily weather records from 1787 until his death, his first book was Meteorological Observations (1793), and he read a series of papers on meteorological topics before the Literary and Philosophical Society
