- HE MADE SEVERAL REMARKABLE METEOROLOGICAL OBSERVATIONS. Dalton’s first major achievements were in meteorology, the scientific study of atmosphere. In 1793, Meteorological Observations and Essays became his first published work.
- He PUBLISHED THE FIRST EVER PAPER ON COLOUR BLINDNESS. John Dalton was colour blind and so was his elder brother Jonathan Dalton. In his 1794 paper “Extraordinary facts relating to the vision of colours” Dalton described the defect he had discovered in his own and his brother’s vision.
- JOHN DALTON DID PIONEERING WORK IN HYDROLOGY. Dalton’s 1799 paper proposed after research and estimated calculations that the quantity of rain and dew are equal to the quantity of water carried off by evaporation and by the rivers.
- HE PROVIDED GREAT NEW INSIGHTS INTO THE NATURE OF GASES. In 1802, John Dalton’s ground-breaking research, which provided great new insights on the nature of gases, was published.
Although a schoolteacher, a meteorologist, and an expert on color blindness, John Dalton is best known for his pioneering theory of atomism. He also developed methods to calculate atomic weights and structures and formulated the law of partial pressures.
He introduced the atomic theory into chemistry. He also researched colour blindness; as a result, the umbrella term for red-green congenital colour blindness disorders is Daltonism in several languages. [ a ][ 2 ] Early life.
