||1971: Royal Rife dies ... inventor and early exponent of high-magnification time-lapse cine-micrography. In the 1930s, he claimed that by using a specially designed optical microscope, he could observe microbes which were too small to visualize with previously existing technology. Rife also reported that a 'beam ray' device of his invention could weaken or destroy the pathogens by energetically exciting destructive resonances in their constituent chemicals. Rife's claims could not be independently replicated, and were discredited by independent researchers during the 1950s.

1802: Mathematician and theorist Niels Henrik Abel born. Abel will make pioneering contributions in a variety of fields, including the discovery of Abelian functions, and the first complete proof demonstrating the impossibility of solving the general quintic equation in radicals.
1816: The British Admiralty dismisses Francis Ronalds's new invention of the first working electric telegraph as "wholly unnecessary", preferring to continue using the semaphore.
1901: "Fightin'" Bert Russell agrees to fight three rounds of bare-knuckled boxing at World Peace Conference.
1910: Mathematician Julius Petersen dies. His famous paper Die Theorie der regulären graphs is a fundamental contribution to modern graph theory.
1914: In Cleveland, Ohio, the first electric traffic light is installed.
1920: Artist George Tooker born. His paintings will depict his subjects naturally, as in a photograph, but the images will use flat tones, an ambiguous perspective, and alarming juxtapositions to suggest an imagined or dreamed reality.
1994: Cryptanalyst and mathematician Solomon Kullback dies. Krullback began his career with the US Army's Signal Intelligence Service (SIS) in the 1930s; when the National Security Agency (NSA) was formed in 1952, Rowlett become chief of cryptanalysis, overseeing the research and development of computerized cryptanalysis.
