John Dalton was the youngest of three surviving children of a Quaker handloom weaver. He was born about Sept. 6, 1766 (no exact record exists), in Eaglesfield. Until he was 11, he attended school, then at the age of 12 became a teacher. For about a year he next worked as a farm helper, but at 15 he returned to teaching, privately for the most part, pursuing it as a career for the remainder of his life.

John Dalton was the first to recognize that the total pressure of a mixture of gases is the sum of the contributions of the individual components of the mixture. By convention, the part of the total pressure of a mixture that results from one component is called the partial pressure of that component. Dalton's law of partial pressures states that the total pressure of a mixture of gases is the sum of the partial pressures of the various components.

John Dalton was born on or about September 6, 1766, to Quaker parents, in Eaglesfield, a remote village in the north of England. He was largely self-educated, and learned most of his mathematics and science by teaching others. He studied mathematics in a local school until the age of 11, started his own school at the age of 12, and at 15 joined his brother Jonathan in teaching at, and later running, a Quaker school in Kendal. The Quakers were a small dissenting (from the established Church of England) sect, and Dalton was ... a nonconformist, like the scientists Joseph Priestley and Michael Faraday. Dalton was taught and influenced by fellow Quakers Elihu Robinson, a wealthy instrument maker, and John Gough, a blind polymath. In Kendal Gough taught the young Dalton Latin, Greek, French, mathematics, and science, and in return Dalton read to him from books and newspapers.

John Dalton (1766-1844) developed the first useful atomic theory of matter around 1803. In the course of his studies on meteorology, Dalton concluded that evaporated water exists in air as an independent gas. He wondered how water and air could occupy the same space at the same time, when obviously solid bodies can't. If the water and air were composed of discrete particles, Dalton reasoned, evaporation might be viewed as a mixing of water particles with air particles. He performed a series of experiments on mixtures of gases to determine what effect properties of the individual gases had on the properties of the mixture as a whole. While trying to explain the results of those experiments, Dalton developed the hypothesis that the sizes of the particles making up different gases must be different.

John Dalton was born on September 6, 1766, in Eaglesfield, England. He was the son of a weaver and received his early education from his father ... at a Quaker school in his hometown, where he began teaching at the age of twelve. In 1781 he moved to Kendal, where he conducted a school with his cousin and older brother. He moved to Manchester in 1793, and lived there the rest of his life as a teacher, fist at New College and later as a tutor. He died on July 27, 1844. Dalton began a series of meteorological observations in 1787, that he continued for fifty-seven years.

John Dalton was born and raised in St. Louis, Missouri, the youngest of seven children. Upon graduation from college, he received a plane ticket to travel around the world, a gift from his brother, Jim. So began an enduring interest in travel and foreign culture. During the late 1980’s, John lived in Taiwan and traveled in Mainland China and other Asian countries. He ... met his wife, Jen Jen Chang, in Taiwan.
