Contribution to the Development of the Atomic Concept
Becquerel discovered the radioactivity of uranium by accident.  Searching for a connection between X rays (recently discovered by Roentgen) and phosphorescence, he placed a covered photographic plate next to a phosphorescent uranium salt.  The plate became exposed even though it had an opaque cover and therefore was not subject to any light.  Becquerel established that some of the radiation emitted by the uranium was deflected by a magnet, unlike X rays; also, the radiation was emitted by all uranium salts, whether phosphorescent or not.  His discoveries led to the receipt of the Nobel Prize in physics for 1903 (shared with Marie and Pierre Curie).
