The chemist, John Dalton was born September 6, 1766. When Dalton was young, all he wanted was a good education but he couldn't get that due to his family being poor. He went to school in his village and later at a young age, he began teaching there to provide for his family. At age 14, he stopped teaching and started working as a farm hand.

Then after that, he started to have an interest in all in all forms of matter and that's when the atomic theory came in. Later on in Dalton's life he continued to teach.

He developed the law of multiple proportions by studying and expanding upon the works of Antoine Lavoisier and Joseph Proust.
Dalton believe the atomic theory could explain why water absorbed different gases in different proportions.
Dalton hypothesized this was due to the difference in the mass and complexity of the gases' respective particles.
Dalton claimed that the forces of repulsion thought to cause pressure acted only between atoms of the same kind and that the atoms in a mixture were different in weight and complexity.
Dalton believed that particles in different gases had different volumes and surrounds of caloric.
He defined partial pressure in terms of a physical
