He based his theory of partial pressures on the idea that only like atoms in a mixture of gases repel one another, whereas unlike atoms appear to react indifferently toward each other. This conceptualization explained why each gas in a mixture behaved independently. Although this view was later shown to be erroneousit served a useful purpose in allowing him to abolish the idea, held by many previous atomists from the Greek philosopher Democritus to the 18th-century mathematician and astronomer Ruggero Giuseppe Boscovichthat atoms of all kinds of matter are alike.
John Dalton, born September 5 or 6,Eaglesfield, CumberlandEngland—died July 27,ManchesterEnglish meteorologist and chemist, a pioneer in the development of modern atomic theory. Early life and education Dalton was born into a Quaker family of tradesmen; his grandfather Jonathan Dalton was a shoemaker, and his father, Joseph, was a weaver.
Joseph married Deborah Greenup inherself from a prosperous local Quaker family.
Dalton was the youngest of their three offspring who survived to adulthood. Two years later the brothers purchased a school in Kendalwhere they taught approximately 60 students, some of them boarders.
As a teacher Dalton drew upon the experiences of two important mentors: Elihu Robinson, a Quaker gentleman of some means and scientific tastes in Eaglesfield, and John Gough, a mathematical and classical scholar in Kendal.
From these men John acquired the rudiments of mathematics, Greek, and Latin. Robinson and Gough were also amateur meteorologists in the Lake District, and from them Dalton gained practical knowledge in the construction and use of meteorologic instruments as well as instruction in keeping daily weather records.
Dalton retained an avid interest in meteorologic measurement for the rest of his life. Early scientific career In Dalton moved to Manchester to teach mathematics at a dissenting academy, the New College.
He took with him the proof sheets of his first book, a collection of essays on meteorologic topics based on his own observations together with those of his friends John Gough and Peter Crosthwaite. This work, Meteorological Observations and Essays, was published in He upheld the view, against contemporary opinion, that the atmosphere was a physical mixture of approximately 80 percent nitrogen and 20 percent oxygen rather than being a specific compound of elements.
He measured the capacity of the air to absorb water vapour and the variation of its partial pressure with temperature. He defined partial pressure in terms of a physical law whereby every constituent in a mixture of gases exerted the same pressure it would have if it had been the only gas present.
