Marcel Proust was a novelist, not a physicist. Joseph Proust was a French chemist who continued Lavoisier's (another French chemist who died in 1794 from radicals involved in the French Revolution) work. In 1799 Proust stated and proved the law of definite proportions (also called "Proust's Law"). This law soon helped John Dalton develop the law of multiple proportions. Always remember to specify which Proust you're talking about, because some people tend to think of Marcel(like I do) when they hear the name, (not to belittle Joseph), hence the first response to your query.
Joseph-Louis Proust discovered the Law of Definite Proportions, which states that chemical compounds always contain the same elements in the same proportions by mass. This finding was significant in understanding the fundamental nature of atoms and their role in chemical reactions.
Joseph Louis Proust's contribution to atomic theory was the law of constant composition which he discovered in 1799. He showed that when chemical reactions occur, matter is not destroyed, nor is it created.
Joseph Louis Proust is the discoverer of the law of definite proportions: a chemical compound contain allways the same proportion of elements, by mass.
Now many exceptions from this law are known: the nonstoichiometric compounds.
Law of Definite Proportions (Law of Constant Composition) - A given compound always has the same elements in the same proportion by mass.

What did Rutherford discover about the volume of the nucleus?
Rutherford discovered that the nucleus occupies a very small volume compared to the overall size of the atom. He found that the nucleus is extremely dense and contains nearly all the mass of the atom, while the rest of the atom is mostly empty space.
What is Joseph Louis proust's model of the atom?
his view of the atom was that all atoms are the same
What did Rutherford discover regarding the structure of 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 year did Aristotle discover the atom?
Aristotle did not discover the atom. The concept of the atom was first proposed by the ancient Greek philosopher Leucippus and his student Democritus around the 5th century BCE. Aristotle, who came after them, did not accept the idea of atoms and instead favored a different view of matter.
What method did Democritus's use to discover atoms?
None, he did not discover the atom. His idea of the atom was derived from Philosophical reasoning not Scientific methods and experiments.
What Dalton discover?
Dalton discovered the particles that make the atom and the atom itself
Did ernest discover the atom?
