Biography

In 1839, his/her father, Antoine Becquerel, discovers the photovoltaic effect which corresponds to the appearance of a tension at the boundaries of a material Semi-conducteur exposed to the Lumière.

Edmond Becquerel occupies the pulpit of physics applied to Arts with the Conservatoire national of arts and trades starting from 1852, and, following his/her father, becomes professor of physique to the national Muséum of natural history. It is interested first of all in the Phosphorescence and the study of the Spectroscopie, managing to obtain thanks to photography a reproduction of the solar spectrum. Thereafter, its research is directed towards the Magnétisme, then the thermal conductibility of gases. In 1866, it takes the first temperature measurements using the Thermopile.

He is elected member of the Academy of Science in 1863 and becomes foreign member of the Royal Society in 1888.

Edmond Becquerel collaborated in some of the works of his father ( Éléments of terrestrial physics and meteorology ). His/her son is Henri Becquerel.
