...atom bomb was the creation of France's long-dead Henri Becquerel, who discovered radioactivity, and the Curies, who discovered radium. It was the creation of Albert Einstein, sitting quietly in an old sweater, keeping his speculative pencil always pointed close to the secrets of physics...
Mass & Energy. In 1896 Henri Becquerel discovered radioactivity, which is the spontaneous release of atomic energy by certain heavy metals. Becquerel had some photographic plates lying in a dark drawer near a bit of uranium; he found the plates lightstruck. His researches led to the discovery of radium by Pierre and Marie Curie, and it was by using radium for cancer therapy that man first harnessed atomic energy to his own ends...
...Antoine Henri Becquerel of France left some uranium salts lying in the dark near a photographic plate. When he developed the plate he found that some sort of rays from the uranium, passing through a metal container and several other obstacles, had left an image on the plate. Thus by accident Becquerel, who shared a Nobel Prize with Pierre and Marie Curie, discovered radioactivity...
...frowned on her efforts to stimulate interest in the Polish language. While studying in Paris she lived in a bare garret, ate meals that cost half a franc a day, met a brooding, handsome young physics instructor whom she twitted for expressing astonishment at her learning, and then married. Becquerel's accidental discovery of radioactivity of uranium compounds in 1896 excited them greatly. They obtained a ton of pitchblende from the Austrian Government, began a long series of crushings, pulverizations, leachings, precipitations, crystallizations with apparatus at which a modern physicist would sneer. Much of the time Mme Curie spent...
...Institut du Radium's Curie Laboratory which she founded in 1912. lecturing at the Sorbonne, writing treatises and books. Then there were the honors which had been showered on her as on no other woman of her time-the Nobel Prize awarded to her, her husband and Becquerel in 1903, to her alone in 1911; the gram of radium presented to her by President Harding in 1921 in behalf of U. S. admirers; the $50,000 given her by President Hoover in 1929. But modest Mme Curie always turned away from such honors, such gifts. At her bedside last...
