John dalton and Democritus used them
Democritus and John Dalton both believed that atoms were indivisible and made up all matter. They shared the idea that atoms were small, solid particles that could not be divided further.
Democritus, an ancient Greek philosopher, first proposed the idea of atoms as indivisible particles. Dalton's atomic theory, developed in the 19th century, expanded on this concept by introducing the idea of atoms combining in specific ratios to form compounds. Dalton's theory built upon and refined Democritus' original idea of atoms, laying the foundation for modern atomic theory.
It was John Dalton in the early 1800s.
John Dalton. N.B.: John Dalton [born: September 6, 1776; died: July 27, 1844, at age 67] was an English chemist and physicist who claimed matter was made up of tiny particles and that these particles were identical for any given kind of matter. Moreover, he claimed these particles were indivisible and could neither be created nor destroyed in any chemical process, only be altered in the manner they were grouped.
Both Dalton and Democritus proposed that matter is made up of indivisible particles called atoms that are different in size and shape. They also believed that atoms are in constant motion and can combine to form different substances.
John Dalton used experiments and scientific tools to study matter.

By using experimental methods Dalton transformed Democritus ideas on atoms into a scientific theory.

He pubish is own atomic theory in 1803 developed his atomic theory by observations gathered from many experiments .
The ancient Greek philosopher Democritus theorized about atoms, and so did Dalton, but Dalton also performed experiments which confirmed the reality of atoms and showed the way for further research.
They both thought the same theory but Dalton had evidence to prove it, unlike Democritus.
