20. Perrin, Jean Baptiste Perrin, Jean Baptiste (18701942) Jean Baptiste Perrin was born in Lille, September 30,1870, where he was educated at the Ecole Normal Sup rieure http://www.cartage.org.lb/en/themes/Biographies/MainBiographies/P/Perrin/Perrin.

Perrin, Jean Baptiste Jean Baptiste Perrin was born in Lille, September 30,1870, where he was educated at the Ecole Normal Supérieure, becoming an assistant in physics during 1894-1897, when he began his researches on cathode rays and X-rays. He received the degree of "docteur ès sciences" in 1897 for a thesis on cathode and Rantgen rays and was appointed, in the same year, to a readership in physical chemistry at the Sorbonne, University of Paris. He became Professor here in 1910; a post which he held till 1940, when the Germans invaded his country. His earliest work was on the nature of cathode rays, and their nature was proved by him to be that of negatively charged particles. He also studied the effect of the action of X-rays on the conductivity of gases. In addition, he worked on fluorescence, the disintegration of radium, and the emission and transmission of sound. The work for which he is best known is the study of colloids and, in particular, the so-called Brownian movement. His results in this field were able to confirm Einstein's theoretical studies in which it was shown that colloidal particles should obey the gas laws, and hence to calculate Avogadro's number N, the number of molecules per grammolecule of a gas. The value thus calculated agreed excellently with other values obtained by entirely different methods in connection with other phenomena, such as that found by him as a result of his study of these dimentation equilibrium in suspensions containing microscopic gamboge 'particles of uniform size. In this way the discontinuity of matter was proved by him beyond doubt: an achievement rewarded with the 1926 Nobel Prize.
