The first person to develop the first model of the atom in 1803 was John Dalton.

John Dalton
In the following order: Heliocentric theory of the solar system (Aristarchus of Samos, 270 BCE) Natural Selection (Darwinian evolution, 1858) Theory of the hydrogen atom (as a small negatively charged particle inside a larger positively charged particle, 1904, the plum pudding model) Theory of relativity (special relativity, 1905) Theory of relativity (general relativity's initial paper on the acceleration of objects within the framework of special relativity, 1907) Theory of the hydrogen atom (as a small particle orbiting the atomic nucleus, 1909, the Rutherford or Planetary model) Theory of the hydrogen atom (as an "electron cloud" surrounding the atomic nucleus, 1913, the quantum mechanical or Bohr model) Theory of relativity (general relativity and its ability to warp space-time, 1915) So heliocentrism was, by about two millenia, the first. Relativity and the model of the hydrogen atom are intricately intertwined, so which came first depends on what you mean specifically.

Master myslon invented the cell theory and came up with it
Two scientists came up with The Cell Theory. It was in 1839, Matthias Schleidan and Theodor Schwann, two German Biologists came up with this theory.
Excepting philosophical atomism John Dalton is the first to elaborate an atomic theory.
democritus was greek philosophers.
He invented atomic power He came up with the theory of Relativity. He came up with the theory of Gravity. He had all these equations like E=mc2
he came up with the theory of atomic numbers
John Dalton
I don't know of atomic theory, but he came up with the idea that light energy acted like packetts of energy that he called photons. Thru some theoretical calculations he came up with Plank's constant that deals with the energy of different wavelengths of light.
atoms combine in whole numbers.
The pre-modern idea of atomic theory was proposed by Greek thinkers like Democritus, Leucippus, and the Epicureans, which would have been at about 500 to 300 BC.
Dalton came up with that theory. It was proven wrong, though.
Einsten was not an inventor. He was a teotherical and theorem scientist. You might hear that he invented the atomic bomb. What he did was make up the theory to split to atom. In other words, he came up with the theory and other people did the invention. Beer came centuries before Einstein.
J.J. Thomson's scientific ideas were called the atomic theory. In 1897 he discovered the electron and came up with a new theory that atoms were made up of small particles.
John Dalton, a pioneer in developing atomic theory, came from England. He was born in Eaglesfield, in Cumberland, England and later moved to Manchester.
