Henri Becquerel announced the discovery of radioactivity

Antoine Henri Becquerel was a physicist, Nobel laureate, and the discoverer of radioactivity. He received the 1903 Nobel Prize in Physics. The SI unit for radioactivity, the becquerel (Bq), is named after him. Becquerel was born in Paris into a family which produced four generations of scientists: Becquerel’s grandfather, and son. He studied engineering. In 1890 he married Louise Désirée Lorieux. In 1892, he became the third …

Ernest Rutherford

New Zealand-born British physicist who became known as the father of chemist and nuclear physics,  succeeded in splitting the atom January 3, 1919. By bombarding nitrogen (N) atoms with alpha particles, he broke down the nucleus of the nitrogen atoms, releasing hydrogen (H) and oxygen (O) atoms in the process. As a result he became the first true alchemist.  In early work he discovered …
