John Dalton is recognised as father of atomic theory. This is because, he was the first researcher to postulate the basic property or a basic model of an atom. He used this postulates for his research in chemistry. Though most of the postulates he stated seemed to be modified in this era. But the concept of a tiny indivisible particle was introduced by him which lead to the research field of atomic particles. Though now they are not indivisible particles any more but still the recognition is given to him for opening a new stream of research.
