John Dalton was an intelligent child, who took an interest in the world around him and tried to learn as much as he could about everything. Dalton attended a Quaker school in his village, when he was just 12 years old he started teaching there. When he was 14, he spent time as an assistant to his brother at a Quaker boarding school in the town of Kendal. Around 1793, Dalton took the position of a math and philosophy tutor at Manchester's New College where he continued teaching himself science, mathematics, Latin, Greek and French. By the 1800's John resigned from tutoring at the college due to financial difficulties. His study of gases led him to wonder about what substances were actually made of. His popular atomic theory was then born.

understanding of atoms

John Dalton is most recognized for his theory about atoms. His atomic theory states that all matter is composed of tiny particles called atoms that cannot be created, divided or destroyed. It also stated that all atoms of the same element are exactly alike and atoms of different elements are different. His theory contributed in the the development of the modern time atomic theory. Without his theory to base our past information on, we wouldn't have discovered the many things we know about atoms today.
