John Dalton Worked As a Teacher at the New College in Manchester

John Dalton and his brother opened a Quaker school in Kendal when they were 15 years old, teaching roughly 60 students. He became principal of the school when he was 19 years old and remained in that position until he was 26 years old. One of the interesting facts about John Dalton is he traveled to Manchester in 1793, when he was 27 years old, to teach mathematics and natural philosophy at the New College, a dissenting academy. He was appointed as a math and natural philosophy teacher.

Dalton spent a lot of time at his makeshift laboratory on George Street, which was the headquarters of the Manchester Literary and Philosophical Society. He investigated and weighed gases he gathered from a pond near Old Trafford while he was there. He wondered aloud how water vapor and oxygen could coexist in the same area. They have to be made up of separate particles. Dalton developed his innovative atomic theory in 1803, based on this fundamental premise, which stated that all substance is made up of atoms. Unfortunately, his notes were destroyed when the building was bombed during WWII.

Dalton's calculations benefited researchers for the large Manchester cotton manufacturers in his day, and they were quickly developing new hues based on his chemical discoveries. Manchester was put on the map of the modern world by John Dalton. In the early nineteenth century, his scientific discoveries changed an industry in which Manchester was the world leader, affected an important field of anatomy, and pioneered our understanding of weather.
