1898 Jan. 23: Electrical engineer and inventor Oliver Blackburn Shallenberger dies. He invented the first successful alternating current electrical meter, which was critical to the general acceptance of AC power.
1898 Feb. 11: Physicist and academic Leo Szilard born. He will conceive the nuclear chain reaction in 1933, and patent the idea of a nuclear reactor with Enrico Fermi.
1898 Feb. 23: Émile Zola is imprisoned in France after writing "J'accuse", a letter accusing the French government of antisemitism and wrongfully imprisoning Captain Alfred Dreyfus.
1898 Mar. 3: Mathematician Emil Artin born. He will work on algebraic number theory, contributing to class field theory and a new construction of L-functions. He will also contribute to the pure theories of rings, groups and fields.
1898 Mar. 12: Mathematician and physicist Johann Jakob Balmer dies. He developed an empirical formula for the visible spectral lines of the hydrogen atom.
1898 Apr. 1: Mathematician and anthropologist William James Sidis born. He will become famous first for his precocity and later for his eccentricity and withdrawal from public life.
1898 Apr. 2: Mathematician Chiungtze C. Tsen born. He will prove Tsen's theorem, which states that a function field K of an algebraic curve over an algebraically closed field is quasi-algebraically closed (i.e., C1).
1898 Dec. 26: Marie and Pierre Curie announce the isolation of radium.
1899 Jan. 21: Physician, confidence trickster, and suspected serial killer John Bodkin Adams is born.
1899 Feb. 18: Mathematician and academic Marius Sophus Lie dies. He largely created the theory of continuous symmetry and applied it to the study of geometry and differential equations.
1899 Apr. 7: Physicist and academic Petrus Leonardus Rijke dies. He explored the physics of electricity, and is known for the Rijke tube (which turns heat into sound, by creating a self-amplifying standing wave).
1899 Apr. 14: Mathematician Gabriel Sudan born. He will discover the Sudan function, an important example in the theory of computation, similar to the Ackermann function.
1899 Aug. 9: Chemist Edward Frankland dies. He was one of the originators of organometallic chemistry, introducing the concept of combining power or valence.
1899 Aug. 16: Chemist and academic Robert Bunsen dies. He investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff.
1899 Aug. 24: Short-story writer, essayist, poet and translator Jorge Luis Borges born. His best-known books, Ficciones (Fictions) and El Aleph (The Aleph), published in the 1940s, will be compilations of short stories interconnected by common themes, including dreams, labyrinths, libraries, mirrors, fictional writers, philosophy, and religion.
1899 Aug. 31: Georg Cantor writes to Dedekind, remarking that his "diagonal process" could be used to show that the power set of a set has more elements than the set itself.
