Antoine Henri Becquerel (December 15, 1852 – August 25, 1908) was a French physicist, Nobel laureate, and one of the discoverers of radioactivity. He inherited a tradition of research from his grandfather, Antoine Cesar Becquerel, who developed the field of electrolysis, and his father, A.E. Becquerel, who invented a new method for spectroscopic analysis. Henri's gifts included his ability to conduct extensive research and develop a summarizing theory which was written as a mathematical formula. He is known for the laws of radiation associated with phosphorescence.
Becquerel's investigations were conducted during a period of new discoveries about energy, including the newly recognized X-rays of Wilhelm Conrad Röntgen. Duplicating Röntgen's experiments led Becquerel to intuitively compare the types of radiation and led him to accept the notion that some radiation comes from within the substance itself rather than by external stimulation, such as in the case of phosphorescence. His discovery of radiation from a uranium salt eventually contributed to a change in the paradigm of classical physics and helped begin the era of atomic physics. His work led to a more detailed understanding of the structure of matter and its relationship to energy.
