John Dalton published his atomic theory in 1803 where he gives 7 postulates on what he determined atoms where at that time.
1.) Matter is composed of extremely small particles call atoms.
2.) Atoms are indivisible and indestructible
3.) Atoms are a given element are identical in size, mass, and chemical properties.
4.) Atoms of a specific element are different from those of another element
5.) Different atoms combine in simple whole-number ratios to form compounds.
6.) In a chemical reaction, atoms are separated, combined, or rearranged.

Yes, John Dalton was an English chemist, meteorologist and physicist. He is best known for his pioneering work in the development of modern atomic theory, and his research into color blindness.
Dalton's new information on atomic weights allowed a Russian chemist, Dmitri Mendeleyev to create the Periodic Table of elements. This table provided the means for discovering new elements, and Dalton also proposed symbols for the elements.
The Law of Multiple Proportions was developed by John Dalton based on the Law of Definite Proportions, was part of what laid the groundwork for his atomic theory, and for the basis of chemical formulas for compounds.English chemist John Dalton
John Dalton, a british chemist, explained that elements are made of atoms and different elements have atoms of different mass

Dalton came up with that theory. It was proven wrong, though.
