Daltons bio

Chemist John Dalton was born September 6, 1766, in Eaglesfield, England. During his early career, he identified the hereditary nature of red-green color blindness. In 1803 he revealed the concept of Dalton’s Law of Partial Pressures. Also in the 1800s, he was the first scientist to explain the behavior of atoms in terms of the measurement of weight. Dalton died July 26, 1844 in Manchester, England.

Dalton's accomplishments

Dalton had created Dalton's Law which explains that the total pressure is equal to the sum of all the pressures of parts, which is for gases.
He had also revived the atomic theory. He was also a member of the Royal Society. He recorded and wrote Meteorological Observations and Essays on the weather conditions. He had investigated the color blindness condition, also known as Daltonism.

John Dalton (1766 – 1844) proposed a basic model of the atom that helped establish many scientific concepts and also created the foundation for more modern models. His model suggested that atoms are the smallest particle of an element, that atoms of different elements have different masses, and that they are solid, indestructible units - much like a billiard ball.
