John Dalton's Main Accomplishments
Chemist and physicist John Dalton was born September 6, 1776, in Eaglesfield, England. During his early career, he identified the hereditary nature of red-green color blindness, a condition that was once called Daltonism. Then 1801 he revealed the concept of Dalton’s Law of Partial Pressures, a law that states that the total pressure exerted by a mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases. Dalton's most remembered accomplishment, however, was the article he wrote for the Manchester Literary and Philosophical Society in 1803 regarding atomic weights, otherwise known as the Atomic Theory.
