developed the idea that the atom was the smallest particle of matter
Democritus, an ancient Greek philosopher, was the first person to introduce the idea of an atom. He proposed that all matter is made up of tiny indivisible particles called atoms. Democritus' atomic theory laid the foundation for the modern understanding of atoms.
Dalton. Dalton's atomic theory stated that atoms are indivisible and indestructible and unchangeable.
The idea is that if you divide it into anything smaller than an atom, it will no longer have the characteristics of that element.
Democritus was the one who came up with the concept and the name (atomos in Greek means "no-cut"). Democritus was mostly lucky, not prescient; the scientific method in ancient Greece largely consisted of coming up with as many wacky ideas as they possibly could, under the theory that eventually someone's wacky idea was bound to be right.
These philosophers were Leukippus and his disciple Democritus.
John Dalton was the first person to propose the idea of the atom as the smallest particle in 1803. However, equipment needed to prove the theory was not available until the late 1900s.

Lamarck
Yes, as far as we know he was the first to theorize about this, although he had no way of proving his theory. He came up with the word "atomos," which is Greek for indivisible. We honor him even today by using the word atom, which is derived from it.
Coining of the term "atom" and the idea that matter was composed of small, invisible, indivisible particles.
The idea that atoms are indivisible.
All matter is formed from indivisible atoms.
The idea that atoms are indivisible and indestructible, and the idea that all atoms of the same element have the same mass.
wave-particle duality a+
The idea of the atom was first proposed by the ancient Greek philosopher Democritus in the 5th century BCE. He suggested that all matter is made up of indivisible particles called atoms, which differ in size, shape, and arrangement.
