2. Marie Pierre Curie and Henri Becquerel were nominated for the Nobel Prize in 1902, but didn’t win.

3. The Curies and Henri Becquerel shared the Nobel Prize for Physics because of their discovery of natural radioactivity.

4. In 1896, Henri Becquerel had inadvertently discovered radioactivity when he left some uranium ore in a drawer on top of an undeveloped photographic plate, on which the uranium left a "shadow."

5. Another scientist named Henri Becquerel had observed the same phenomenon when the plates were placed underneath a uranium salt, and placed in the sun.

6. Henri Becquerel wondered if the fluorescence bore any relationship to the recently discovered X - rays.

7. In fact, the first found to be a man named Henri Becquerel.

8. In fact, it was Curie that coined the term radioactivity, though Henri Becquerel discovered the phenomenon years earlier.

9. Radioactivity came to light a century after the discovery of uranium when Henri Becquerel used uranium salts and photographic plates in the same experiment and found that one fogged the other.
