Origin of becquerelAfterAntoine Henri Becquerel
Family of French physicists, including Antoine César (1788-1878), a pioneer in electrochemistry; his son Alexandre Edmond (1820-1891), noted for his research on phosphorescence and spectroscopy; and his grandson Antoine Henri (1852-1908), who shared a 1903 Nobel Prize for his discovery of the radioactive properties of uranium.
