Early Life:

• Born September 6, 1766 in Eaglesfield, England.

• Started teaching at a Quaker school in Cumberland when he was 12.

• During his early career as a scientist he studied color blindness, also know as “Daltonism”.

John Dalton:

His Ideas: • Matter is composed of

atoms.• Atoms are indestructible

and indivisible.• Atoms of a given element

are identical in size, mass, and chemical properties.

His Ideas Continued:

• Atoms of a specific element are different from a different element.

• Different atoms combine in simple whole number ratios to form compounds.

• Chemical reaction- atoms are separated, combined, or rearranged.

Models:

Dalton’s Law of Partial Pressures:

• Total pressure of a mixture of gases is equal to the sum of the pressures of all the gases in the mixture.

His Books:

• Meteorological Findings • A New System of

Chemical Philosophy

• Dalton and the Contribution of Self-Observation to Scientific Discovery: An Account of Colour Blindness

Accomplishments:

• The president of the Manchester Literary and Philosophical society.

• Accepted an honorary Doctorate of Science degree from Oxford University.

• Offered another degree, a Doctorate of Laws by Edinburgh University.

His Contributions to Science/Chemistry:

• His research not only changed chemistry, but also initiated its advancement into modern science.

• The splitting of the atom could not have happen if he hadn’t researched the atomic makeup of simple and compound molecules.

• Allowed for cost-efficient manufacturing of chemical compounds.

Later Life:• Continued to teach at

universities throughout the Untied Kingdom.

• Lived an uncomplicated life focused on science.

• Had a stroke in 1837.

• Suffered a second stroke.

• Died July 26, 1844 at his home in Manchester, England.

• 40,000 people attended the procession, honoring him and his accomplishments.
