He was a member of the Academy of Sciences, became its President, and was elected to the far more influential post of permanent Secretary. In 1878, Henri Becquerel assumed the position of assistant in the Muséum, taking the place left free by his own father.. Antoine Henri Becquerel was the third in a line of four generations of scientists. He was born in Paris into a family of great scientists. For more than a century, the Becquerel family worked in the same laboratory in the Jardin des Plantes, later called the Muséum d’Histoire Naturelle, in Paris. Antoine Henri Becquerel (1852-1908) Contributions: Received the Noble Prize in physics for being the first to discover radioactivity as a phenomenon separate from that of x-rays and document the differences between the two. His father, Alexander Edmond Becquerel, was a professor of applied physics at École Polytechnique in Paris and had researched solar radiation and phosphorescence. Both his grandfather and his father were successively professors of physics at the Musée d'Histoire Naturelle in Paris. Radioactivity was a big part in the Atomic Theory because it proved that there are smaller particles in an atom that makes it up, there are protons, neutrons, and electrons. Antoine Henri Becquerel (December 15, 1852 - August 25, 1908) was a French physicist, Nobel laureate, and one of the discoverers of radioactivity. Antoine Henri Becquerel (15 December 1852 – 25 August 1908) was a French physicist, Nobel laureate, and the discoverer of radioactivity along with Marie Skłodowska-Curie and Pierre Curie, for which all three won the 1903 Nobel Prize in Physics. In 1896, French scientist Henri Becquerel discovered that uranium minerals could expose a photographic plate through another material. December 13, 2011, 7:00AM ANS Nuclear Cafe Paul Bowersox. Discovery of Radioactivity: Becquerel Antoine Henri Becquerel (1852-1908; view photo at Access Excellence, at the National Health Museum) was the third of four Becquerels to hold a chair of physics at the Paris Museum of Natural History and to belong to the Academy of Sciences, following his grandfather Antoine César, his father Alexandre Edmond, and preceding his son Jean. BECQUEREL, Antoine-Henri (1852-1908). Becquerel presumed that uranium emitted some invisible light similar to X-rays, which were recently discovered by W.C.Roentgen. After the crystal had soaked up some sunshine, Antoine Becquerel placed it on a … French postage stamp (1946) : Antoine Henri Becquerel (1852 – 1908) French physicist, Nobel laureate ... (1859–1906) and an illustration of his discovery of uranium extracted via pitchblend. For work in this field he, along with Marie Skłodowska-Curie (Marie Curie) and … The beginning of a theory. Becquerel s discovery, which marks the beginning of modern nuclear physics, was stimulated by Wilhelm Roentgen’s discovery of X-rays in November 1895. BECQUEREL, ALEXANDRE-EDMOND (1820–1891) Edmond Becquerel was one of a family of scientists. Antoine Henri Becquerel. This earned him the Nobel Prize in Physics in 1903. What does becquerel mean? Antoine H Becquerel (1852-1908) was a French scientist renowned for his work and subsequent discovery into the evidence of radioactivity for which he was awarded the Nobel Prize for physics in 1903. Antoine Henri Becquerel (1852-1908) is known as the man who discovered radioactivity—a discovery that influenced the development of atomic weapons, nuclear energy, and radioactive medical treatments.
