Short Summary
Antoine Henri Becquerel was a pioneering French physicist known for his discovery of radioactivity, a breakthrough that paved the way for future research in nuclear science. Born into a family of distinguished scientists, his groundbreaking findings earned him the 1903 Nobel Prize in Physics, which he shared with Marie and Pierre Curie. His work laid the foundation for the development of atomic energy and profoundly influenced the fields of physics and chemistry.
Early Life & Education
Henri Becquerel was born on December 15, 1852, in Paris, France, into a family with a rich scientific heritage. His father, Alexandre-Edmond Becquerel, and grandfather were both prominent physicists, which undoubtedly influenced his early interest in the sciences. He attended the Lycée Louis-le-Grand and later pursued higher education at the École Polytechnique, where he received a solid grounding in engineering and physics. He furthered his studies at the École des Ponts et Chaussées, preparing him for a career that would blend his engineering skills with scientific inquiry.
Career Highlights
Becquerel began his career as an engineer in the Department of Bridges and Highways, but his passion for research soon led him to academia. He became a professor at the Museum of Natural History in Paris, where he focused on optics and magnetism. His most significant career highlight came in 1896 when he discovered natural radioactivity while experimenting with phosphorescent materials and their effect on photographic plates. This accidental discovery marked a turning point in his career and dramatically advanced the scientific understanding of atomic physics.
