In 1790 Dalton seemed to have considered taking up law or medicine.

Although he was very interested with his projects his family didn’t encourage him.

Daltons famous investigation was about the atomic theory in chemistry.

Dalton earned his living mostly by teaching. Also by public speaking.

After he taught at a Quaker Boarding school for ten years, he later moved to Manchester to another teaching position.

In Manchester he became part of the Manchester Literary and Philosophical Society, which helped him with motivating academic environment and laboratory facilities.

His first paper he wrote to the society was on the topic “color blindness.” After he wrote about that, he was later called "Daltonism."

Dalton kept meteorology records from 1787 until his death in 1844.

His first book he wrote was Meteorological Observations (1793).

Also Dalton read series of papers about meteorological topics.

The papers and books he read was about Charles’s Law. (gas law)

Meteorology

Dalton was best known as The weather pioneer who advocated atomic theory

Dalton was one of the first scientist who decided that all matter is made up of small particles, or atoms.

John Dalton Father of Modern Atomic Theory

Daltons Atomic Theory

1) All matter is made of atoms. Atoms are indivisible and indestructible

2) All atoms of a given element are identical in mass and properties

3) Compounds are formed by a combination of two or more different kinds of atoms.

4) A chemical reaction is a rearrangement of atoms.

Dalton had prepared for this idea with his development of two gas laws.A rule for the pressure of a mixture of gases (the law of partial pressures)

And one for the way volume changes with temperature (called Charles's law, although first stated by Dalton).
