“Matter, though divisible in an extreme degree, is nevertheless not infinitely divisible. That is, there must be some point beyond which we cannot go in the division of matter… I have chosen the word “atom” to signify these ultimate particles.” – John Dalton. John Dalton is a British chemist who was born in September 6, 1766 in Eaglesfield, England and died on July 26, 1844 in Manchester, England. At the age of 12, he started teaching at a Quaker school in Cumberland. Dalton worked as a farmhand but then returned to teaching at the age of 14. He became the principal of a Quaker School in Cumberland four years later.

After that the orange, yellow, and green seem one color which descends pretty uniformly from an intense to a rare yellow, making what I should call different shades of yellow.” – John Dalton. In 1794, John Dalton published the very first paper on colorblindness called “Extraordinary facts relating to the vision of colors.” Included in the paper, he wrote about his own experience with the disease. Dalton’s theory regarding colorblindness was incorrect, although, he was correct that colorblindness was hereditary. Dalton believed that the shortage is color perception was due to the discoloration of a liquid medium called aqueous humour. He believed that because of the blueish aqueous humour it filtered out all of the other colors. Among his death, he had an autopsy done of his eyes and there was no found bluish liquid, proving his belief …show more content…
After he told the world about relative weights at Manchester Literary and Philosophical Society, he was invited to the Royal Institution of London to recreate his announcement. Dalton’s atomic theory started to receive a lot of publicity and debate after the word was out. Scientist either immediately accepted or they remained skeptics for years to come. Davy was among one of the skeptics who did not want to accept that Dalton was right, eventually after many experimental tests the work was confirmed and about 50 years later Davy accepted that Dalton was correct. From 1817 until his death, John Dalton was elected as president of Manchester Literary and Philosophical society. He was awarded the Society’s Royal Medal for his atomic theory in
