||1828: Alexander Ross Clarke born ... geodesist who made calculations of the size and shape of the Earth (the Clarke ellipsoid) were the first to approximate accepted modern values with respect to both polar flattening and equatorial radius. The figures from his second determination (1866) became a standard reference for U.S. geodesy for most of the twentieth century until satellites could improve accuracy. In 1880, Clarke coined the term "Geodesy" when he published his famous book by that title.

||Gottfried Schapper (b. 16 December 1888) was a German listening specialist, before and during World War II. Gottfried Schapper, was an Signals intelligence officer, who was known for having the original idea for the Forschungsamt signal intelligence agency. Schapper had worked in the Reichswehr Ministry cipher bureau from 1927 to 1933, which would later form part of Luftwaffe signals intelligence unit, had been dissatisfied by both the scope of monitoring and intercept work and the incompetence of the methods employed there. He along with some colleagues, including the convinced Nazi, Hans Schimpf, proposed to Hermann Göring that a separate signals office be created that would be free from department ties.
