Henri Becquerel

French physicist and Nobel laureate, 1852-1908

"In 1903, Becquerel shared the Nobel Prize in Physics with Pierre and Marie Skłodowska-Curie ""in recognition of the extraordinary services he has rendered by his discovery of spontaneous radioactivity"". The SI unit for radioactivity, the becquerel (Bq), is named after him. There is a crater called Becquerel on the Moon and also a crater called Becquerel on Mars. Besides the Nobel Prize, Becquerel received some othe important awards such as Rumford Medal (1900), Helmholtz Medal (1901), Barnard Medal (1905), and Toffie Medal (1908)."

Becquerel writes research notes on molecular X- rays, electrolysis, ions, etc., which is part of Becquerel's own work related to radioactivity. Becquerel writes in his hand scientific notes about ions, electrolysis, atoms, molecules, positive charges of the ions and how they react, he writes several long formulas, including: “e/e=l,n=rx10 to the power of 19,and then explains how e/u= 10 to the power of 7, 2x 1000 […] of the electrolysis v (S 10 to the power of 4 ), l/2000 of the atom dissolving middle body”. - Manuscripts by Becquerel discussing his work on radioactivity are of great rarity. Becquerel whose experiments with uranium salts led to the discovery of spontaneous radioactivity; for this breakthrough he shared the 1903 Nobel Prize for Physics with Marie and Pierre Curie.
