Edmond Becquerel was one of a family of scientists. His father, Antoine-Cesar, was professor of physics at the Museum d Histoire Naturelle, and his son, [Antoine-] Henri Becquerel, also a physicist, discovered the phenomenon of radioactivity (for which he received the Nobel Prize in 1903). 

Antoine-Henri Becquerel, 1852-1908. French physicist and engineer. Discoverer of the rays emitted by uranium. He carried out important researches on rotatory magnetic polarization, phosphorescence, infrared spectra, and radioactivity. His grandfather Antoine-Cesar-Becquerel (1788-1878), and his father, Alexandre-Edmond Becquerel (1820-1891), also made many important contributions to chemistry and physics. 

Antoine-Henri Becquerel was bom the son of the physicist Alexandre-Edmond Becquerel, and the grandson of the physicist Antoine-Cesar Becquerel, and it is not surprising that he followed in their footsteps. It is also not surprising that his research interests centered around solar radiation and phosphorescence, as these are phenomena that his father had investigated. He entered the Ecole Polytechnique, in Paris, in 1872, which he left in 1874 and to which he subsequently returned. Becquerel received a doctorate degree from the Faculty of Sciences of Paris in 1888. In 1892, he was appointed professor of applied physics in the Department of Natural History at the Paris Museum, and in 1895, professor of physics at the Ecole Polytechnique. 

Antoine Cesar Becquerel in France (1855) and Pavel Yablochkov in Russia (1877) have built electrochemical devices, using coal anodes in a molten potassium nitrate electrolyte. William Jacques (1896) obtained a US patent for his invention of a coal stack with a coal anode and an iron cathode immersed into molten alkali hydroxide. Despite the great doubts raised, as to the nature of the processes taking place in the stack, the electrical performance of this fuel cell stack, operating at temperatures from 400 to 500°C, had a rather impressive total power 1.5 kW, and current densities up to... 

Antoine Cesar Becquerel (Ch tillon-sur-Loing, Dept. Loiret, 8 March 1788-Paris, 18 January 1878), ancient Chef de bataillon de Genie (1808-14), from 1837 professor of physics at the Musee d Histoire Naturelle, author of a... 

Becquerel, Antoine Henri (1852-1908) A French physicist who accidendy discovered the existence of radioactivity in 1896. By chance, he put away in a drawer some unexposed photographic plates wrapped in black paper. In the drawer there was also a specimen of uranium salt Later, the plates were found to be fogged and led to the conclusion that the uranium had emitted radiation that was sufflciendy powerful to penetrate the wrapping. In 1903 he was awarded the Nobel Prize for physics with Marie and Pierre Curie. His father (Antoine Cesar) and grandfather (Alexandre Edmond) were also eminent physicists and the three held, one after the other, the position of professor of physics at the Musde d Histoire Naturelle from 1837 to 1908.
