jun 19, 1896 - Henri Becquerel

Description:

a French physicist, reads of William Roentgen's experiments with X-rays, and learns that they can cause certain materials to fluoresce.

Becquerel eventually discovers that the uranium in this compound is the magic ingredient. All compounds with uranium in them will fog a photographic plate; compounds without uranium will not. Becquerel therefore calls the new radiation "uranic rays".
