He became a Professor at the Polytechnic in 1895. Antoine Henri Becquerel. Antoine Henri Becquerel was the third in a line of four generations of scientists. Becquerel was born in Paris, the 15th of December 1852. Curie never worked on the Manhattan Project, but her contributions to the study of radium and radiation were instrumental to the future development of the atomic bomb. To verify his theory he carried out an experiment: wrap a photographic plate in black paper (to protect it from direct light), place a . Radioactivity demonstrated that the atom was neither indivisible nor immutable. Nice work! Becquerel was born in Paris, France on December 15, 1852. In 1896, French scientist Antoine Henri Becquerel discovered radioactivity which was an early contribution to atomic theory. =Becquerel's earliest work was concerned with the plane polarization of light, with the phenomenon of phosphorescence and with the absorption of light by crystals (his doctorate thesis). Explore the research that went into his theory, and his breakthrough in. For more than a century, the Becquerel family worked in the same laboratory in the Jardin des Plantes, later called the Muséum d'Histoire Naturelle, in Paris. Henri Becquerel, in full Antoine-Henri Becquerel, (born December 15, 1852, Paris, France—died August 25, 1908, Le Croisic), French physicist who discovered radioactivity through his investigations of uranium and other substances. Henri Becquerel Antoine Henri Becquerel (1852-1908) was a French physicist and winner of the 1903 Nobel Prize in Physics. Click to see full answer What did Henri Becquerel discover about uranium?
