In 1896 the French physicist Henri Becquerel noticed that pitchblende had one very unusual property: photographic plates exposed to a sample of pitchblende reacted as if they had been exposed to light.

However, the investigation of what caused the radioactivity was to lead to one of the most significant discoveries in science, a discovery that laid the foundations for modern nuclear physics.
