John Dalton.
He proposed the first widely recognized atomic theory (around 1803–1808). Key postulates: elements are made of indivisible atoms, all atoms of a given element are identical, atoms of different elements have different weights, atoms combine in simple whole-number ratios to form compounds, and atoms are neither created nor destroyed in chemical reactions.
