1900
Atomic theory: Leucippus (approx. 500 BC) and Democritus (approx. 460-370 BC).
Theory of relativity:
* special relativity - Albert Einstein, 1905
* general relativity - Albert Einstein, 1916
There are two different theories; the Special Theory of Relativity was published in 1905, the General Theory of Relativity, in 1916.
Relativity in 1905
Atomic theory about 2500 years ago - by the Greeks.
Einstein
1900s
Relativity was 1905, various "atomic" theories go back 2500 years to the Greeks.
Albert Einstein developed a Theory of Relativity which helped lead to the development of atomic energy. He also worked on the Manhattan Project to help create the world's first nuclear bomb.
The basic theory was first discussed and proposed by Bernoulli.
When speaking of Relativity, people mostly think of Albert Einstein. However, Relativity was experimented by Galileo Galilei first. So when speaking of Relativity, it helps to be specific: Einsteinian Relativity or Galilean Relativity.
In 1905, he published a paper on theory of relativity which can be considered as his first invention.
Relativity was 1905, various "atomic" theories go back 2500 years to the Greeks.
1905
Albert Einstein developed the theory of relativity. He first proposed the special theory of relativity in 1905 and later developed the general theory of relativity in 1915. These theories revolutionized our understanding of space, time, and gravity.

If you think its relativity you are wrong.
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.
Niels Bohr.Father Roger Boscovich is often credited as the father of modern atomic theory, according to Thomas E. Woods, Jr., author of the book How the Catholic Church Built Western Civilization
The scientific Theories of General and Special Relativity were first proposed by Albert Einstein.Special Relativity in 1906 and General Relativity in 1916.
1905
The basic theory was first discussed and proposed by Bernoulli.
Lynn Margulis first proposed the theory of endosymbiosis.
