* Henri Becquerel: He is credited with the discovery of radioactivity itself in 1896. He accidentally discovered that uranium salts emitted invisible rays that could expose photographic plates, even in the dark.
* Marie Curie: Along with her husband, Pierre Curie, she conducted extensive research on radioactivity, coining the term "radioactivity". She discovered the radioactive elements polonium and radium, and was the first woman to win a Nobel Prize, and the only person to win Nobel Prizes in two different scientific fields (Physics and Chemistry).
* Pierre Curie: A physicist who worked alongside Marie Curie, he played a key role in the research on radioactivity, particularly in developing techniques for measuring and characterizing radioactive materials. He also discovered the piezoelectric effect.
* Ernest Rutherford: Known as the "father of nuclear physics", he conducted groundbreaking experiments on radioactivity, including the discovery of alpha and beta particles and the development of the Rutherford model of the atom. He also pioneered the field of nuclear physics.
* Frederick Soddy: He is known for his work on radioactive decay, particularly for the discovery of isotopes. His research led to the understanding of how elements transform into other elements through radioactive processes.
These scientists laid the foundation for our understanding of radioactivity, which has had a profound impact on various fields, including medicine, energy production, and scientific research.
