Jean Baptiste Perrin Net Worth

Jean Baptiste Perrin was born on September 30, 1870 in Lille, France, French, is Physicist. Jean Baptiste Perrin was a renowned French physicist who was honored with the Nobel Prize for Physics in 1926. He began his career as an assistant in physics, and after the completion of his doctorate, got the opportunity to teach as a lecturer and then professor. Among his students was well-known physicist Pierre Victor Auger. As part of his research, he was able to prove several scientific theories including the Brownian motion and atomic nature of matter. He also determined the Avogadro’s number and electric charge of cathode rays through his studies. He was regarded by many as the founding father of the National Centre for Scientific Research. Jean Baptiste Perrin was awarded the Nobel Prize for Physics for ‘his work on the discontinuous structure of matter and especially for his discovery of sedimentation equilibrium’. He had also written and published several books and dissertation papers based on the research work he conducted.

Born in Lille, France, Perrin attended the École Normale Supérieure, the elite grande école in Paris. He became an assistant at the school during the period of 1894–97 when he began the study of cathode rays and X-rays. He was awarded the degree of docteur ès sciences (PhD) in 1897. In the same year he was appointed as a lecturer in physical chemistry at the Sorbonne, Paris. He became a professor at the University in 1910, holding this post until the German occupation of France during World War II.


In 1895, Perrin showed that cathode rays were of negative electric charge in nature. He determined Avogadro's number (now known as the Avogadro constant) by several methods. He explained solar Energy as due to the thermonuclear reactions of hydrogen.


Perrin was also the recipient of numerous prestigious awards including the Joule Prize of the Royal Society in 1896 and the La Caze Prize of the French Academy of Sciences. He was twice appointed a member of the Solvay Committee at Brussels in 1911 and in 1921. He also held memberships with the Royal Society of London and with the Academies of Sciences of Belgium, Sweden, Turin, Prague, Romania and China. He became a Commander of the Legion of Honour in 1926 and was made Commander of the Order of Léopold (Belgium).


After Albert Einstein published (1905) his theoretical explanation of Brownian motion in terms of atoms, Perrin did the experimental work to test and verify Einstein's predictions, thereby settling the century-long dispute about John Dalton's atomic theory. Carl Benedicks argued Perrin should receive the Nobel Prize in Physics; Perrin received the award in 1926 for this and other work on the discontinuous structure of matter, which put a definite end to the long struggle regarding the question of the physical reality of molecules.


In 1919, Perrin proposed that nuclear reactions can provide the source of Energy in stars. He realized that the mass of a helium atom is less than that of four atoms of hydrogen, and that the mass-energy equivalence of Einstein implies that the nuclear fusion (4 H → He) could liberate sufficient Energy to make stars shine for billions of years. A similar theory was first proposed by American Chemist william Draper Harkins in 1915. It remained for Hans Bethe and Carl Friedrich von Weizsäcker to determine the detailed mechanism of stellar nucleosynthesis during the 1930s.


In 1927, he founded the Institut de Biologie Physico-Chimique together with Chemist André Job and Physiologist André Mayer. Funding was provided by Edmond James de Rothschild. In 1937, Perrin established the Palais de la Découverte, a science museum in Paris.


Perrin is considered the founding father of the National Centre for Scientific Research (Centre National de la Recherche Scientifique (CNRS)). Following a petition by Perrin signed by over 80 Scientists, among them eight Nobel Prize laureates, the French education minister set up the Conseil Supérieur de la Recherche Scientifique (French National Research Council) in April 1933. In 1936, Perrin, now an undersecretary for research, founded the Service Central de la Recherche Scientifique (French Central Agency for Scientific Research). Both institutions were merged under the CNRS umbrella on October 19, 1939.


Perrin was an atheist and a socialist. He was an officer in the Engineer corps during World War I. When the Germans invaded France in 1940, he escaped to the U.S.A., together with his partner Nine Choucroun. He died in New York City. After the War, in 1948, his remains were transported back to France by the cruiser Jeanne d'Arc and buried in the Panthéon.
