A biography of english chemist and physicist john dalton

He received his early education from his father and from Quaker John Fletcher, who ran a private school in the nearby village of Pardshaw Hall. Dalton's family was too poor to support him for long and he began to earn his living at the age of ten in the service of a wealthy local Quaker, Elihu Robinson. Around the age of 23 Dalton may have considered studying law or medicine, but his relatives did not encourage him, perhaps because being a Dissenterhe was barred from attending English universities.

Inhe completed his first degree in electrical engineering. He published his first paper, a mathematically elegant solution of a problem involving eddy currentsin At Aachen, he studied under the theoretical physicist Arnold Sommerfeldwho later claimed that his most important discovery was Peter Debye.

InSommerfeld received an appointment at MunichBavariaand took Debye with him as his assistant. Debye got his Ph.

Inhe derived the Planck radiation formula using a method which Max Planck agreed was simpler than his own. Inwhen Albert Einstein took an appointment as a professor at PragueBohemiaDebye took his old professorship at the University of ZurichSwitzerland.

He was awarded the Lorentz Medal in From to he was the president of the Deutsche Physikalische Gesellschaft. In May he became member of the Royal Netherlands Academy of Arts and Sciences and in December of the same year he became foreign member. They had a son, Peter P. Debyeand a daughter, Mathilde Maria born Peter became a physicist and collaborated with Debye in some of his researches, and had a son who was also a chemist.

In consequence, the units of molecular dipole moments are termed debyes in his honor. In —, Debye calculated the effect of temperature on X-ray diffraction patterns of crystalline solids with Paul Scherrer the " Debye—Waller factor ".

Also inDebye developed a theory to explain the Compton effectthe shifting of the frequency of X-rays when they interact with electrons.

Later work[ edit ] From to Debye was director of the physics section of the prestigious Kaiser Wilhelm Institute in Berlin. These positions were held during the years that Adolf Hitler ruled Nazi Germany and, from onward, Austria.

After leaving Germany in earlyDebye became a professor at Cornell, chaired the chemistry department for 10 years, and became a member of Alpha Chi Sigma. In he became an American citizen.

Unlike the European phase of his life, where he moved from city to city every few years, in the United States Debye remained at Cornell for the remainder of his career. He retired inbut continued research until his death. This started as a result of his research during World War II on synthetic rubberbut was extended to proteins and other macromolecules.

In AprilDebye suffered a heart attackand in November of that year a second one proved fatal. Rispens discovered documents that, as he believed, were new and proved that, during his directorship of the Kaiser Wilhelm SocietyDebye was actively involved in cleansing German science institutions of Jewish and other "non-Aryan elements".

In light of the current situation, membership by German Jews as stipulated by the Nuremberg laws, of the Deutsche Physikalische Gesellschaft cannot be continued.

According to the wishes of the board, I ask of all members to whom these definitions apply to report to me their resignation.

He planned his departure from Germany during a visit with his mother in Maastricht in lateboarded a ship in Genoa in January and arrived in New York in early February He immediately sought a permanent position in the US and accepted such an offer from Cornell in June That month, he crossed the US border into Canada and returned within days on an immigration visa.

He was able to get his wife out of Germany and to the US by December Further, Rispens [9] alleges that Albert Einstein in the first half of actively tried to prevent Debye from being appointed in the United States at Cornell.

Einstein allegedly wrote to his American colleagues: Van Ginkel [12] investigated FBI reports on this matter and traced the "reliable source" to a single letter directed to Einstein and written by someone whose name is lost.

This person was not known personally to Einstein and, according to Einstein, probably did not know Debye personally either. Moreover, this accusatory letter did not reach Einstein directly but was intercepted by British censors who showed it to Einstein. Einstein sent the British agent with the letter to Cornell, and the Cornell authorities told Debye about the affair.Watch video · Chemist John Dalton was born September 6, , in Eaglesfield, England.

Michael Faraday: Michael Faraday, English physicist and chemist whose many experiments contributed greatly to the understanding of electromagnetism. The English chemist John Dalton () provided the beginnings of the development of a scientific atomic theory, thus facilitating the development of chemistry as a separate science.

His contributions to physics, particularly to meteorology, were also significant.

John Dalton . Biography of John Dalton, Chemist and Physicist John Dalton was a British chemist and physicist. He was born on September 5, , in the small town of Eaglesfield in England.

Although a schoolteacher, a meteorologist, and an expert on color blindness, John Dalton is best known for his pioneering theory of atomism.

He also developed methods to calculate atomic weights and structures and formulated the law of partial pressures.
