Theories about the composition of matter date back to the ancient Greeks. In about 450 BC, Democritus theorized that matter consisted of átomos (means uncuttable), or atoms. Modern realization of atomic theory began in 1661 when Robert Boyle therorized that there was an end to the ability of chemistry to break down substances (he called atoms "corpuscules"). Up to that point, classical chemists thought substances were formed from combinations of the 4 classical elements: air, earth, fire, and water. Then, in 1789 the term "element" was defined by the Frenchman Antoine Lavoisier to mean basic substances that could not be further broken down by the methods of chemistry. From there, John Dalton proposed that gases were made of individual particles that could combine to form unique compounds. By 1905, the existence of atoms was pretty much universally accepted when Einstein published his papers on Brownian motion (random motion due to the energy in atoms). Sorry, but atoms were never really just "found", they were gradually noticed over centuries, and now it's accepted as the best explanation for what we can see.

∙ 12y ago1. Some Indian thinkers supposed the existence of atoms 2 600 years ago.
2. Separately, in Europe, Leucippus and Democritus supposed the existence of atoms 2 500 years ago.
3. The same supposition in the Middle Age by John Boyle.
4. John Dalton founded the modern atomistic theory in 1805.
But many philosophers, chemists and physicists worked during a long history to establish the today knowledge about atoms; see the link below.
