Nothing. He contributed to the evolving body of speculation about the atom, by translating Epicurus who had developed his ideas from Leucippus and Democritus; but nothin to its history
Lucretius wrote a poem called "De Rerum Natura" ( The Nature Of Things ) which helped the atomic theory survived.
Neil bohr has done research in quantum mechanics.
He determined the number of positive charges in the nucleus of an atom. He was the first one to bring the concept of atomic number.
I think it was that he theorized that when a new substance is made, the elemnts didn't change the atoms just rearranged. I'm not certain though. Galileo is more known for his research on planets.
He proposed the wave-particle duality for the electrons.
Dalton's atomic theory was a major contribution to discover the atomic structure in despite of been completely counterproved.
Antoine Lavoisier was a French nobleman and chemist. His contribution to the development of the modern atomic theory was his idea of the possibility of an Atomic Mass.
The contribution of anyone prior to about 1600 to the development of atomic theory might as well be "nothing whatsoever." Democritus and/or Leucippus contributed the name "atomos", but not much else; they were wrong about nearly every detail. John Dalton is just about the earliest scientist to have had any significant contribution to atomic theory, and most of what we now consider atomic theory was developed since about 1900.

Atomic Theory
They didn't help with atomic theory, they created it.
That the cake is a lie.

The most important contribution of Werner Heisenberg was the discovery of the uncertainty principle.
