John Dalton

John Dalton was born on September 6, 1766 in Eaglesfield, England in the UK. He only had 2 other siblings because the rest never made it through birth. He and his brother were color-blind. They were a poor family but were able to afford a good education. But, because the family were Quakers, his education opportunities were limited(“John Dalton”). He attended a school until he was 11, and then started helping as a teacher. At the age 19, he was the principle of the school. In the first half of 1793, when he was 26, Dalton took the position of teacher at Manchester’s New College and taught natural philosophy and mathematics. By 1794, he wrote his first scientific paper called Extraordinary Facts Relating to the Vision of Colors. His theory was at first wrong, but he was the first person to research it (“John Dalton”). They gave it the name Daltonism. Daltonism is colorblindness, …show more content…
Now that he had figured out all this about gases, he wondered what gases were made of. 2000 years before, the same question was asked and answered by Democritus. He called them atoms but no one knew of his statement was true. It was now Dalton’s quest to find it out. (“John Dalton”). Dalton eventually came to an agreement with Democritus. He said that gas was made of atoms and what atoms were made of. A few years afterward, a man named Amedeo Avogadro came back and changed some of Dalton’s errors. However, his changes were rejected for many years later. This is mainly because it mainly disagreed with Dalton’s work(“John Dalton”). Later on in his life, Dalton came up with 5 theory's. First, that all matter is made of atoms no exceptions. Second, atoms are indivisible and indestructible. Third, all atoms of an element are identical in both mass and properties. Fourth, compounds are made by two or more different kinds of atoms combined. Lastly, a chemical reaction is a rearrangement of atoms (“John
