Henri Becquerel was a French scientist, physicist and one of the most important personalities in the history of radioactive research. Becquerel belonged to a family of scientists and scholars. Both his father and grandfather were scientists, which is why it almost seemed like a natural progression for him to follow in their footsteps once he started attending his formal training in scientific studies at some of the best institutes in Paris. After completing his engineering degree he took up a job and at the same time he was deeply involved in phosphorescence research. Later, he directed his research towards discovering new radioactive elements. His research in the field of radioactivity won him the Nobel Prize for Physics in the year 1903. Henri Becquerel was deeply associated with the National Musuem of Natural History when his father was the chair of physics and following his stellar work as a researcher he became the chair of physics at the same institution. Becquerel is without doubt one of the greatest physicists in the field of radioactivity and the world of science will forever be indebted to him.
