It was not discovered as it did not then exist, we had to invent it ourselves.
It was actually Max Planck and others who 'quantized' matter, and even light, after Newton and Boscovitch.
The first atomic theories go back to ancient Greece and India 2000 to 3000 years ago. The idea of atoms was first proposed in the 5th century B.C. by the philosophers Leucippus and Democritus. However, the formal exposition of a science based atomic theory was made by John Dalton, who lived 1766 - 1844.
The modern atomic theories originated between 1789 and 1799 but did not reach its current form until the early 1930s when Werner Heisenberg incorporated Quantum Theory into Ernest Rutherford's model of the atom.
That is a question everyone is asking about. There is no answer. Sorry, I too am on the search for this answer. I'll be sure to get back to you after I have some answers!!
the kinetic theory of matter was discovered in 1616
The particle theory of matter states that matter is composed of tiny particles that are always in constant motion.

Dalton's Atomic Theory
Excepting philosophical atomism John Dalton is the first to elaborate an atomic theory.
Niels Bohr.Father Roger Boscovich is often credited as the father of modern atomic theory, according to Thomas E. Woods, Jr., author of the book How the Catholic Church Built Western Civilization
The idea that led to the atomic theory of matter, was John Dalton.
John Dalton first pursued research into atomic theory. He was the first person to propose the existence of the atomic structure.

john dalton developed the atomic theory , which he published in 1803
Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements. But Moseley hadn't a personal atomic theory, he was not the discoverer of the atomic theory.
