What did Joseph-Louis Proust discover in regarding the atom?
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.

Who provided foundation for john Dalton's work on atomic structure?
The work of chemists such as Antoine Lavoisier, Joseph Proust, and Amedeo Avogadro provided the foundation for John Dalton's work on atomic structure. Lavoisier's law of conservation of mass, Proust's law of definite proportions, and Avogadro's hypothesis on equal volumes of gases played key roles in shaping Dalton's atomic theory.
