The Full Story
Henri Becquerel discovered radioactivity in 1896 while studying uranium compounds. He noticed that uranium salts exposed photographic plates even when kept in the dark, revealing a spontaneous emission from the material itself. His finding opened the field later developed by Marie and Pierre Curie, who coined and expanded the study of radioactivity. It was a turning point in modern physics and chemistry.
