John Dalton

1766-1844

 

  He was an English Quaker chemist who taught mathematics and physics at New College, Manchester, England. In his New System of Chemistry (three parts: 1808, 1810, 1827) he suggested how atoms can be used to explain chemical reactions. He postulated a one-for-one combination of atoms to demonstrate specific summations of weights of the elements to form compounds. Dalton was colorblind and scientifically described this malady. Red-green colorblindness is some-times known today as “daltonism.”
