Henri Becquerel [1852-1908] In 1897 when Henri Becquerel researched the newly discovered X-rays it led to studies of how uranium salts are influenced by light. By accident, he discovered that the uranium salts spontaneously emitted a penetrating radiation that could be registered on a photographic plate. Further studies made it clear that this radiation was something new - not the same type as X-rays. He had discovered a new phenomenon - radioactivity. [by Félix Nadar]

Antoine Henri Becquerel December 1852 – 25 August was a French physicist, Nobel laureate, and the discoverer of radioactivity along with Marie Skłodowska-Curie and Pierre Curie, for which all three won the 1903 Nobel Prize in Physics.
