There are three parts to Dalton's Theory of Atoms.
All things are made up of atoms
Atoms are indivisible and unbreakable/indestructible
Compounds are formed by a combination of two or more atoms that are different
john dalton develop an atomic theory in 1803, based on idea of the atomic exsiting
The atomic theory of matter can be attributed to the ideas proposed by the ancient Greek philosopher Democritus. He hypothesized that all matter is composed of indivisible and indestructible particles called atoms, which differ in shape, size, and arrangement. Democritus' atomic theory laid the foundation for modern atomic theory.
John Dalton further developed Democritus's ideas by proposing the modern atomic theory, which stated that each chemical element is composed of its own unique kind of atom. Dalton's theory also included the concept that atoms are indivisible, and that chemical reactions involve the rearrangement of atoms.
It was John Dalton in the early 1800s.
The first modern atomic theory was proposed by John Dalton in the early 19th century. Dalton's theory stated that all matter is made up of tiny, indivisible particles called atoms, and that atoms of different elements have different masses and properties.

John Dalton: In the late 1700s, John Dalton developed the atomic theory on which all current understandings are based.
john dalton developed the atomic theory , which he published in 1803
The term used by Democritus to identify the particles of an element is atomic theory. It was thought up by John Dalton between the years 1766 and 1844.

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.
In my textbook it sayes that actually Dalton believed that all substances are made of atoms, and this was part of his atomic theory, which he published in 1803.
