Edmond Becquerel: A Passion for Light. Online Celebration of the 200th Anniversary of Edmond Becquerel’s Birth. December 7th, 2020


Edmond Becquerel (1820-1891) was born on March 24th. He was the son of Antoine Becquerel (1788-1878) and the father of Henri Becquerel (1852-1908), discoverer of the natural radioactivity and Nobel Prize in Physics (1903) with Pierre and Marie Curie. He conducted his research and teaching at the Museum National d’Histoire Naturelle and at the Conservatoire National des Arts et Métiers. He was a member and then the president of the French Academy of Sciences (1880). He is behind major advances in the study of the effects of light on materials, with in particular the discovery of the photovoltaic effect (1839), the invention of the first color photography process (1848) and the invention of the phosphoroscope (1858). Though his work is recognized worldwide, he remains relatively unknown in France. The celebration of its 200th birth anniversary is an opportunity to re-discover his exceptional scientific contributions and current relevance.
