Modern atomic theory is generally said to begin with John Dalton, an English chemist and meteorologist who in 1808 published a book on the atmosphere and the behavior of gases that was entitled A New System of Chemical Philosophy.
Democritus was an ancient Greek philosopher who was very interested in matter. He wanted to know what things are actually made of. He was the person who developed the idea of atoms. The word atom comes from the Greek word atomos which means uncuttable.. Democritus believed that if you tried to cut matter into the smallest pieces possible, you would eventually get a very small particle that is indestructible and could not be cut.
