The idea that led to the atomic theory of matter, was John Dalton.

The two earlier scientists whose ideas Dmitri Mendeleev combined were Antoine Lavoisier and John Dalton. Lavoisier established the law of conservation of mass, while Dalton introduced the atomic theory by proposing that all matter is composed of atoms. Mendeleev built upon these concepts to develop the periodic table of elements.
John Dalton is known for his atomic theory, which proposed that all matter is made of tiny, indivisible particles called atoms. He also introduced the concept of relative atomic masses and the idea that chemical reactions involve the rearrangement of atoms.
Democritus was an ancient Greek philosopher who was a pupil of Leucippus. Democritus suggested that different types of small discrete particles formed all matter. He suggested that the properties of the tiny particles are what determined the property of the matter.
Democritus' ideas were not useful in a scientific sense at the time because they were not supported by empirical evidence and lacked experimental verification. Additionally, his atomic theory was an abstract concept that was not mathematically or experimentally testable with the technology available in his era. It wasn't until much later, with advancements in technology and the development of modern physics, that atomic theory was revisited and eventually validated.
The ideas about matter proposed by Democritus in ancient Greece were most similar to what scientists use today. Democritus believed that matter is made up of tiny, indivisible particles called atoms, which is consistent with our modern understanding of matter at the atomic and subatomic levels. His ideas laid the foundation for the development of modern atomic theory.

Leukippos and his student Demokritos proposed intuitively the atomic theory of matter. Some ideas are also in old Sanskrit writings. For the entire history see the link below.

One scientist who made important contributions to atomic theory is John Dalton. He is known for his work on the atomic theory of matter, proposing that all matter is made up of tiny, indivisible particles called atoms. His ideas laid the foundation for modern chemistry.
The development of the atomic theory is primarily attributed to the ancient Greek philosopher Democritus. He proposed that all matter is made up of tiny, indivisible particles called atoms. His ideas laid the foundation for modern atomic theory.
Democritus, an ancient Greek philosopher, became renowned for his development of the atomic theory around the 5th century BCE. His ideas about the structure of matter laid the foundation for modern atomic theory.
John DaltonA2. Many scientists contributed to our present ideas - they did not (and have not yet) sprung full blown into existence. JJ Thomson et al developed some of the atomic theory, but even today the full concept of quarks and gluons may elude us - perhaps to be embodied in string theory.
The ancient Greek philosopher Democritus proposed that matter is composed of indivisible particles called atoms, a theory that is similar to the modern atomic theory in physics. His ideas on the existence of atoms and their properties foreshadowed many aspects of today's scientific understanding of matter and its structure.
John Dalton's atomic theory did not support Aristotle's ideas; in fact, it contradicted them. Aristotle believed that matter was continuous and composed of four elements (earth, water, air, fire), while Dalton proposed that matter is made up of indivisible atoms, which are the fundamental building blocks of all substances. Dalton's theory laid the groundwork for modern chemistry, moving away from Aristotle's qualitative approach to a quantitative understanding of matter.
Aristotle rejected the atomic theories of Democritus and Leucippus because he believed matter was continuous and not made up of indivisible particles. This rejection led to the dominance of Aristotle's views on matter for the next 2000 years, hindering the progress of atomic theory until the scientific revolution in the 17th century.
