The Nobel Prize Winner: Jean Baptiste Perrin

Jean Baptiste Perrin was born in 1870 in France. He was awarded the Nobel Prize in physics in 1926 for determining and explaining the nature of cathode-rays as well as for the Brownian motion. He began to study x-rays while you was working as an assistant and soon after he received his doctorate degree in science. He became a lecturer in physical chemistry a later a professor at the University of Paris. Through his research he was able to show xrays were made of corpuscles with negative electric charge. When Albert Einstein published his theoretical explanation of the Brownian motion in terms of atoms, he went ahead and did all the experimental work that would verify that Einstein’s predictions were true. This was the primary reason why he was awarded the Nobel Prize as well as for his work on the discontinuous structure of matter which was able to put to rest the long struggle in regard to the question of physical reality of various molecules.
