Ecole polytechnique France Obtained docteur-ès-sciences degree in engineering 1888. Education and training After his early schooling at the Lycée Louis-le-Grand, Henri received his formal scientific education at the 1872—74 and engineering training at the École des Ponts et Chaussées Bridges and Highways School; 1874—77. The previous year Wilhelm Rontgen discovered X-rays, a discovery that shocked the scientific community. Becquerel was interested in —the effect utilized in glow-in-the-dark stars, in which light is emitted from a material when exposed to electromagnetic radiation, which persists as a glow even after the radiation is removed.

Nuclear reactors, of course, provide a way of releasing atomic energy more controlled and more slowly. Nobel Lectures: Physics, 1901-1921 1964 , published by the Nobel Foundation, includes a biographical sketch of Becquerel as well as his Nobel lecture on radioactivity. Timeline of Major Events in the Life of Henri Becquerel, 1852-1908 Taking a similar educational route as his father and grandfather, Becquerel studied engineering at Polytechnic. After completing his engineering degree he took up a job and at the same time he was deeply involved in phosphorescence research. Becquerel belonged to a family of scientists and scholars. When one then develops the photographic plate, one recognizes that the silhouette of the phosphorescent substance appears in black on the negative. Quite convincing when it can then find a photographic film, a crystalline image appears above it.

The material radiates if it is in an excited state with the help of electromagnetic radiations of if it is made up of highly charged and energized particles. Radioactivity is a process during which unstable nuclei release energy. Dates December 15, 1852 — August 25, 1908 Authorized Form of Name Becquerel, Henri, 1852-1908 Additional Forms of Names Becquerel, Antoine Henri, 1852-1908 Becquerel, Antoine-Henri, 1852-1908 Biography Henri Becquerel was a nuclear physicist at the École Polytechnique, specializing in radiation and radioactivity. Becquerel became the physics chair of the Museum in 1892. Rothman, Tony, Everything's Relative: And Other Fables from Science and Technology New York, New York: Wiley, 2003 Chapter 5 pages 46—52. Becquerel wisely decided to undo the original project and replace it with an investigation of the strange phenomenon that happened.

For the discovery of natural radioactivity, which for a number of years was called Becquerel rays, he won the Nobel Prize in physics in 1903. His research in the field of radioactivity won him the Nobel Prize for Physics in the year 1903. He was interested in science from a young age because he was surrounded by scientists. He showed an interest in science when he was a student. Today, Becquerel is remembered for discovering radioactivity, a process by which an unstable nucleus emits particles. His first experiments appeared to show this.

At first Becquerel was convinced that he had found a new X-ray source. In 1894, he became chief engineer in the Department of Bridges and Highways. Father: Alexandre-Edmond Becquerel physicist, b. His son went on to become a scientist just like his father, grandfather, and great-grandfather. In 1878 he succeeded in the chair of his father who was professor of applied physics at the Conservatoire des Arts et Métiers. Phosphorescence is a phenomenon in which a substance emits light following exposure to radiation, and continues to exhibit an afterglow once radiation is removed. His father was the head of physics at the Museum.

He thus confirmed his view that something very similar to X rays was emitted by this luminescent substance at the same time it threw off. Describing them to the French Academy of Sciences on 24 February 1896, he said: One wraps a Lumière photographic plate with a bromide emulsion in two sheets of very thick black paper, such that the plate does not become clouded upon being exposed to the sun for a day. Henri Becquerel's Lab Becquerel rechecked his experimental results and finally arrived at the conclusion that uranium salts constantly radiate some rays which effect photographic plates. Radioactive is important for several reasons. Personal Life And Death Henri Becquerel married Janin with whom he had one child, a son by the name Jean Becquerel. After placing sheets of sulfate of uranium on photographic plates wrapped in black paper, he exposed the package to light for several hours.

Henri Becquerel: Biography & Discovery

henri becquerel biography

Becquerel was born December 15, 1852 in Paris, France, to Alexandre-Edmond Becquerel and Aurelie Quenard. His findings while researching led him to become a member of the Academie des Sciences in the year 1889. Before 1895 there was no theoretical view that radioactive phenomena existed. The award was presented to him by The Royal Society. Königliche Akademie der Wissenschaften Berlín Member. His first academic situation was in 1876 as assistant teacher at the École Polytechnique, where in 1895 he succeeded to the chair of. He left a rock and a well-wrapped photographic plate in his desk drawer and found later that the plate, though unexposed to light, had developed patterns which would ordinarily indicate exposure.

His second son, Alexandre Edmond Becquerel, 1820—91, succeeded his father, in 1878, as professor at the Muséum d'Histoire naturelle. Conservatoire national des arts et métiers France Chair of Applied Physics. In 1895, he transitioned to a professorship appointment at Polytechnic. Another discovery was the circumstance that the allegedly active substance in uranium, uranium X, lost its radiating ability in time, while the uranium, though inactive when freshly prepared, eventually regained its lost radioactivity. His son, Antoine , 1852—1908, was professor at the École polytechnique, Paris, from 1895.

Becquerel had long been interested in the phosphorescence, the emission of light of one color following a body's exposure to light of another color. This provides a great snapshot of his life as an accomplished scientist. For the discovery of natural radioactivity, which for a number of years was called Becquerel rays, he won the Nobel Prize in physics in 1903. The most interesting aspect of these rays is the energy it contains. In 1878 he succeeded in the chair of his father who was professor of applied physics at the Conservatoire des Arts et Metiers.

henri becquerel biography

His father was an accomplished Professor of Applied Physics who researched solar radiation. It was here that in 1896 he made a great discovery that made his name famous. He was born into a family of scientists. Becquerel did not have time before his next conference on March 2 and decided to develop the photographic plates anyway, even though his samples had received little sunlight. Henri Becquerel, along with Pierre and Marie Currie, received the Nobel Prize in Physics in 1903. The unit for radioactivity, which measures the amount of that is released when an experiences , is also named after Becquerel: it's called the becquerel or Bq. Both his father, Alexandre Edmond Becquerel, and his grandfather, Antoine Cesar Becquerel, were scientists.
