Discovery of Radioactivity by Henri Becquerel

115 years ago, in 1896 Henri Becquerel while investigating phosphorescence in uranium salts accidentally discovered radioactivity. He was born on December 15, 1852. In honour of his birthday, here is a good historical read on this life changing discovery: http://ansnuclearcafe.org/2011/12/13/henri-becquerels-discovery-of-radioactivity/ ... "The Nobel Prize in Physics 1903 was divided, one half awarded to Antoine Henri Becquerel "in recognition of the extraordinary services he has rendered by his discovery of spontaneous radioactivity", the other half jointly to Pierre Curie and Marie Curie, née Sklodowska "in recognition of the extraordinary services they have rendered by their joint researches on the radiation phenomena discovered by Professor Henri Becquerel": http://www.nobelprize.org/nobel_prizes/physics/laureates/1903/ ... and also: http://www.nobelprize.org/nobel_prizes/physics/laureates/1903/becquerel-bio.html
