释义
Becquerel, Antoine Henri (1852–1908)

Physics
  • His early researches were in optics; then, in 1896, he accidentally discovered radioactivity in fluorescent salts of uranium. Three years later he showed that it consists of charged particles that are deflected by a magnetic field. For this work he was awarded the 1903 Nobel Prize, which he shared with Pierre and Marie Curie.


Chemistry
  • His early researches were in optics, then in 1896 he accidentally discovered radioactivity in fluorescent salts of uranium. He then became an early pioneer in the systematic study of radioactivity. For this work he was awarded the 1903 Nobel Prize for physics, which he shared with Pierre and Marie Curie.


Chemical Engineering
  • A French physicist who accidently 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 sufficiently powerful to penetrate the wrapping. In 1903 he was awarded the Nobel Prize for physics with Marie and Pierre Curie. His father (Antoine César) and grandfather (Alexandre Edmond) were also eminent physicists and the three held, one after the other, the position of professor of physics at the Musée d’Histoire Naturelle from 1837 to 1908.
