Biography of Alexandre-Edmond Becquerel
Alexandre-Edmond Becquerel was a French physicist and the son of Antoine César Becquerel. Born on March 24, 1820, in Paris, France, he had a remarkable career in the field of science.
Early Career
Becquerel began his career as a professor at the Conservatory of Crafts and Arts, where he taught various subjects. He also served as a professor and administrator at the Agronomic Institute and the Natural History Museum. His dedication to education and research earned him recognition in the scientific community.
Scientific Contributions
Becquerel's first published work focused on the study of the solar spectrum and electric light, which was published in "Comptes rendus de l’Acad. aes sc." between 1839 and 1841. He made significant contributions in various areas of physics, including the laws of heat generation during the passage of electric currents and the effects of sunlight on matter.
Working in collaboration with his father, Becquerel conducted extensive research on electricity and phosphorescence. A major part of their findings was documented in their comprehensive work "La lumière, ses causes et ses effets" (Light: Its Causes and Effects), published in Paris between 1867 and 1868 in two volumes.
Becquerel also collaborated with other scientists on diverse projects. He worked with Cahoars to determine the refractive powers of liquids and conducted electrochemical research with Fremy. His experiments covered topics such as the separation of electricity in galvanic batteries, electrical phenomena resulting from the illumination of objects, thermoelectric investigations, the effects of magnetism on matter, and the phosphorescence induced by sunlight.
Contributions to Color Photography
Becquerel's experiments in color photography of the spectrum yielded imperfect results. The colors in the images obtained on silver surfaces were not well-preserved and gradually faded when exposed to light. Although his attempts, along with those of Victor Pespce de Saint-Victor, were pioneering efforts in preserving natural colors in photography, they lacked the means to fix the obtained colors.
It was not until January 1891 that French scientist Gabriel Lippmann announced his success in obtaining and fixing color images of the spectrum. This breakthrough marked a significant advancement in color photography.
Legacy
The extensive range of Becquerel's research, although not fully listed, demonstrates the breadth of his scientific investigations. Many of his works were published in "Annales de chim. et de phys." and "Comptes rendus de l’Acad. des sciences." Despite reaching the age of 72, Becquerel continued to engage in scientific pursuits and remained dedicated to the advancement of knowledge.
Alexandre-Edmond Becquerel, a talented and esteemed scientist, made valuable contributions to the field of physics. His dedication to research and education established him as a prominent figure in the scientific community.
