Historical Background

Henri Becquerel was the discoverer of radioactivity and shared the 1903 Nobel Prize for Physics with Marie and Pierre Curie for this discovery. In 1896 whilst engaged in following up the work of Röntgen regarding what are now known as X-rays, he found that a lump of uranium, wrapped in photographic plates, caused the plates to become fully exposed even before exposure to the light.

He was born in Paris into a family of scientists: in 1892, he became the third in his family to hold the chair of physics at the Muséum National d'Histoire Naturelle. Following his discovery described above, he received the Nobel Prize as noted, and in 1908 was elected Permanent Secretary of the Académie des Sciences. He died at the age of 55 in Le Croisic (Loire-Atlantique) in the year 1908.

The SI unit of radioactivity, the becquerel (Bq), is named in his honour.
