In the 5th cent. B.C. the Greek philosophers Democritus and Leucippus proposed that matter was made up of tiny, indivisible particles they called atom, or in Greek "a-tomos". The reason why they assumed this is because nothing can come from nothing. Around 1803, John Dalton (1766-1844) developed the first useful atomic theory of matter. He imagined the atom as a sphere full of an electrically positive substance mixed with negative electron. Then in 1897, Thompson discovered the first component part of the atom: the electron, a particle with a negative electric charge.
Discovery of the AtomBy the 19th century, technology had advanced greatly and many elements had been discovered to work with. Using the available elements scientist such as John Dalton and Amedeo Avogadro forced them to interact with one another. From these interactions they were able to prove the existence of the atom.
AnswerThat depends on exactly what you mean by "discovered."
Jainism had a concept of small particles similar to atoms in the 6th millennium BC, and either Democritus or his mentor Leucippus (or possibly both together) independently came up with the idea (and the word "atomos", which is Greek for "uncuttable") in the 5th century BC. However, these were essentially lucky guesses; there was no real scientific basis behind them, so saying these people "discovered" atoms is a pretty big stretch.
The best candidate is probably John Dalton, who in the early 19th century proposed (based this time on experiments) that substances were composed of tiny discrete particles, and even assigned relative weight values to several types of these particles. The word Democritus had used was "Englishified" slightly to come up with the modern word "atom" to refer to these particles.
AnswerJohn Dalton was the first who introduced the idea of atom. Atom, the very word, means inseparable or indivisible. Based on that idea in chemistry many laws have been stated such as, law of coservation of mass, law of multiple proportions etc etc.

What did Einstein discover about atom?
Einstein discovered that atoms had protons and neutrons.
What did Ernest Rutherford discover about the structure of an atom?
Rutherford discovered the atomic nucleus and the proton. Rutherford don't discovered the atom. A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
What did Rutherford learn about the atom from his gold-foil experiment?
Rutherford discovered that atoms are mostly empty space except for the nucleus at the center of the atom.
