Nobel Prize in Physics Recipient. Antoine Henri Becquerel was a French engineer known for being the discoverer of radioactivity, which earned him the 1903 Nobel Prize for Physics. Graduated in Engineering at the Ecole Nationale des Ponts et Chaussées, he devoted his research to optical physics, and more specifically to the infrared rays. In 1888, Becquerel obtained his Doctorate of research by a thesis on the absorption of light in crystals, and thanks to this he was appointed member of the Académie des Sciences. During his years of teaching at the Ecole Polytechnique he accidentally discovered the phenomenon of radioactivity, which in 1903 earned him the Nobel Prize for Physics along with Pierre and Marie Curie. Becquerel wrote and published several works, including "Recherches sur les variations des Spectres of absorption dans les crystals", "Travaux de physique et de radiographie optique", "Sur le rayonnement de l'uranium sur diverses propriétés physiques et du rayonnement radioactifs des corps". The unit of measurement of the "Système international d'unités" for the radioactivity and a derivative of uranium ore were dedicated to him.
