| Bemærkning | Edgar Rubin (1886 – 1951) was a Danish psychologist. He was professor of psychology at the university of his native Copenhagen. He is remembered for his work on figure-ground perception as seen in such optical illusions as the Rubin vase.
Rubin's laws governing the selection of the figure were phenomenological in the tradition of Husserl. They did not explain why a figure was selected but merely stated the conditions under which one structure among possible alternatives was selected. Although not a Gestalt psychologist himself, Rubin's ideas were quickly incorporated into Gestalt theory. Niels Erik Nørlund (1885 – 1981) was a Danish mathematician. Nørlund's first publication was in 1905 when he published a paper on a known double star in Ursa Major which, with careful measurements of their orbits, he was able to deduce was actually a triple system with a third star which was too faint to observe. In the summer of 1910, he earned a Master's degree in astronomy and in October of that year he successfully defended his doctoral thesis in mathematics. In 1912 he was appointed to a new chair of mathematics at the university in Lund in Sweden. He became professor of mathematics at Copenhagen University in 1922. He also studied seismology and, in 1925, set up seismographic stations in Denmark and Greenland. In 1928 he persuaded the Danish government to set up a Geodesic Institute. Harald Bohr (1887 - 1951) was a Danish mathematician and brother of Niels Bohr. Harald studied mathematics at the University of Copenhagen. He entered the University in 1904 and quickly became a well known Danish personality, not for his mathematics but rather for his soccer skills. He was in the Danish football team which was placed second in the 1908 Olympic games in London. he became professor of mathematics in the Polytechnic Institute in Copenhagen in 1915. Then, in 1930, he was appointed professor of mathematics at the University of Copenhagen. Harald Bohr worked on Dirichlet series, and applied analysis to the theory of numbers. Bohr's interest in which functions could be represented by a Dirichlet series led him to devise the theory of almost periodic functions. He founded this theory between the years 1923 and 1926 and it is with this work that his name is now most closely associated. |
