Lot 146: Henri Becquerel

French physicist (1852-1908) 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. Desirable unsigned handwritten scientific research notes, one page, 8.75 x 6.25, no date. Becquerel pens research notes about ions, electrolysis, atoms, molecules, and positive charges of the ions and how they react, including several formulas, such as: "e/e=l," and "n=r10 to the power of 19." He 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." In fine condition. Manuscripts by Becquerel discussing his work on radioactivity are of great rarity.
