Demicritus (Solid Sphere Model)
Lived from 460BC - 370BC. He was an ancient Greek philosopher, and today he is remembered for this formation of an atmoic theory of the universe. He also created the solid sphere model, -
John Dalton (Origin of Atomic Theory)
Lived from September 6, 1766 to July 27, 1844. He was a english chemist, meteorologist and a physicist. He was best known for his work in the development of the modern atomic theory. He also identified the hereditary nature of red-green color blindness, and in the 1800s, he was the first scientist to explain the behavior of atoms in terms of the measurement of weight. He created The Origin of Atomic Theory. -
