Henri Becquerel (1852-1908)
In 1896 Henri placed a uranium containing out on a photographic plate in the sun. After removing the crystal he saw that the stone had left an image on the plate, then the weather became cloudy and he put the crystal in a drawer with the plate. Some days latter he came back to see that even without a power source the rock produced energy. Thus Radiation was discovered. Henri Becquerel -
