Born
Antoine Henri Becquerel (15 December 1852 – 25 August 1908) was a French experimental physicist who shared the 1903 Nobel Prize in Physics with Marie and Pierre Curie for his discovery of radioactivity. He also identified that beta particles are high-speed electrons, made observations that laid the groundwork for Ernest Rutherford's theory of radioactive transmutation, and noted the physiological effects of radioactivity which sparked medical applications as radiotherapy.
