Democritus-Born 460 BCE Abdera-Died 370 BCE
He was an Ancient Greek philosopher, the most influential, of the pre-Socratic philosophers was one of the two founders of ancient atomist theory. He elaborated a system originated by his teacher Leucippus into a materialist account of the natural world.

John Dalton-6 September 1766 – 27 July 1844
He was an English chemist, meteorologist and physicist. He is best known for his pioneering work in the development of modern atomic theory, and his research into colour blindness (sometimes referred to as Daltonism, in his honour). He proceeded to calculate atomic weights from percentage compositions of compounds, using an arbitrary system to determine the likely atomic structure of each compound.

G.J. Stoney-1874 - 1891, 26 March, George Johnstone Stoney coins the word "electron" as a fundamental unit of charge
George Johnstone Stoney (1826-1911) presented a paper which contained the first modern conception of the electron.
Therefore, all substances contain the same kind of negative particles he referred to as "corpuscles". GJ Stoney proposed the name "electrons" for these particles in 1894. Information -
James Clerk-Scottish Physicist, Arguably Greatest 19th Century Scientist
Maxwells work in the field of electromagnetismSaturn's rings, the molecular behaviour of gases, and trichromatic theory of colour, have had a major impact in the world. Read more: http://great-scientists.suite101.com/article.cfm/james_clerk_maxwell_biography#ixzz0TI2loPSL Picture -
James Maxwell: physical and mathematical theories of the electromagnetic field.
He started out by writing a paper entitled "On Faraday's Lines of Force" (1856), in which he translated Faraday's theories into mathematical form. He then published "On Physical Lines of Force" (1861). Maxwell's formulation of electricity and magnetism was published in A Treatise on Electricity and Magnetism (1873). Maxwell published his views on the limitations of the Second Law in Theory of Heat (1871). Information -
Dmitri Mendeleev- Born 8 February 1834 (1834-02-08) Verhnie Aremzyani, Russian Empire
Died 2 February 1907 (aged 72) St. Petersburg, Russian Empire
He was a Russian chemist and inventor. He is credited as being the creator of the first version of the periodic table of elements. Using the table,
He predicted the properties of elements yet to be discovered.
He arranged the 63 known elements into a Periodic Table based on atomic mass, which he published in Principles [picture](Picture- http://www.encyclopedie-enligne.com/Images/2/250px-dmitri_mendeleev.jpg) -
J.J. Thompson-Treatise on the Motion of Vortex Rings which won him the Adams Prize in 1884.
Application of Dynamics to Physics and Chemistry appeared in 1886, and in 1892 he had his Notes on Recent Researches in Electricity and Magnetism published. These lectures were subsequently published as Discharge of Electricity through Gases (1897). Information -
Hantaro Nagaoka: Japanese physicist (1865-1950)
Nagaoka led to speculation that the electrons turning around the atomic nucleus would slowly lose energy and ultimately collide with the nucleus. Information -
Robert a. Millikan. 1910
As a scientist, Millikan made numerous momentous discoveries, chiefly in the fields of electricity, optics, and molecular physics. His earliest major success was the accurate determination of the charge carried by an electron, using the elegant "falling-drop method"; he also proved that this quantity was a constant for all electrons (1910), -

Diffraction occurs with electromagnetic waves, such as light and radio -
1941 Schrodinger
He was intrested in the other scientist discoverys like Bhor and he would go over them and see if they where right or if they need to add things. -
James Chadwick 1932
He discovered the fundumental of the domain under the nuclean science.
