Willem de Sitter (1872-1934),
Erst durch Hubbles Entdeckung der Fluchtgeschwindigkeit der Galaxien gewannen de Sitters Theorien erneut an Bedeutung, da sie Hubble erst dazu anregten, den verschiedenen direkten Hinweisen zur Expansion des Weltalls nachzugehen.
Weitere Arbeitsgebiete de Sitters waren die Theorie der Bewegung der Jupitermonde und die Schwankungen in der Rotationszeit der Erde.

Willem Jacob Luyten
By Arthur Upgren
WILLEM LUYTEN WAS THE central figure in the determination of the stellar luminosity function, the frequency function of stars by their luminosity. In this, his major research contribution, he followed in the tradition of Dutch astronomers, mostly of the Leiden Observatory, which began before 1900 with J. C. Kapteyn and included P. J. van Rhijn, Ejnar Hertzsprung, Willem De Sitter, and Jan H. Oort. Luyten was one of a number of distinguished students of these scientists who emigrated to the United States and had a memorable career. His contemporaries included Bart J. Bok, Dirk Brouwer, Gerard P. Kuiper, Jan Schilt, Kaj Aa. Strand, and Peter van de Kamp. Luyten spoke of his ancestry as part French, originating in Provence in the fourteenth century. The family name may have been Lutin and derived from lute players and minstrels attending the popes who resided in Avignon. In 1377 the popes moved back to Rome and the progenitor lute player resettled at the Court of Burgundy. The dukes there united the cities of Holland, and during ducal rule over the next century, the family may have found its way to the Netherlands. His mother's family name of Francken reveals her origin there. Luyten, himself, was born of parents of North Holland, who had settled in Indonesia, then a colony of the Netherlands. His birth on March 7, 1899, was in the city of Semarang in north-central Java, where his father taught French in the local high school. Luyten lived there until 1912, when the family moved back to the Netherlands. At that time he spoke Dutch and French; he also became fluent in German and English before his high school graduation. Later in college he mastered Latin and Greek, and still later, he picked up some Spanish and Italian, and finally, in 1927, Russian. He was rightfully proud of his ability to learn to read and speak so many languages.

WILLEM DE SITTER
Willem de Sitter est le fils d'un juge, président de la cour à Arnhem aux Pays-Bas. Il fait ses premières années d'études dans cette ville. Il s'inscrit plus tard à l'Université de Groningen, en physique mathématique, où il prépare un doctorat. De 1897 à 1899, il travaille à l'Observatoire royal de Capetown, en Afrique du Sud, avec David Gill. Puis, il revient à Groningen où il travaille avec Kapteyn jusqu'en 1908. Cette années-là, il est nommé professeur à l'Université de Leiden et, de 1919 jusqu'à sa mort, il sera directeur de l'Observatoire de Leiden. L'un des premiers à s'intéresser à la relativité générale d'Einstein, il en comprend mieux que quiconque les implications cosmologiques. C'est en partie grâce à lui si l'expédition anglaise de 1919, visant à vérifier la relativité, peut avoir lieu. Il entreprend de répandre la théorie dans les milieux scientifiques, principalement par la parution de trois articles sur " La théorie de la gravitation d'Einstein et ses conséquences astronomiques ", parus en 1916 et en 1917. C'est dans le troisième article qu'il introduit ce qui deviendra " l'univers de de Sitter ". Selon de Sitter, la relativité générale peut servir à montrer que l'univers est en expansion ; Einstein prédisait, au contraire, un univers statique. Suite à l'interprétation que donne Hubble des spectres des galaxies lointaines, Einstein se range du côté de de Sitter. Les travaux ultérieurs de de Sitter, joints à ceux de Lemaître, d'Eddington et de Gamow ont donné naissance à la cosmologie moderne.

Appendix 4: Brief Comments of Willem de Sitter and Albert Einstein On Curved Space
in Appendix 11 That space might differ significantly from a simple Euclidean model was hypothesized rather often in the first two or three decades of the twentieth century. The Friedmann models became popular in the mid 1930s, and the gravimetric considerations in those models seemed to indicate that space could be curved one way or the other, but probably not enough to affect its basic appearance as an expanding sphere within our Hubble horizon. We have traditionally been assumed to be "inside" this sphere, seemingly at its center - as any position would appear to be - with a "radius" currently thought to be around 13 to 14 billion light years in every direction. As we look back in time, we are actually looking into eras where the universe had not had as much time to expand as it has in the current era, that is, in the nearby universe. In fact, if we could look out far enough, the universe would seem to shrink to virtually nothing (or nearly so). This "virtually nothing" position is called the "singularity", and the conventional cosmological wisdom assumes that it is receding at the speed of light. You've probably never seen the universe depicted as anything other than an expanding Euclidean sphere, which still doesn't make it right and may be nothing more than improper Pavlovian conditioning.

The Theoretical Science Establishment Controls Cosmological And Biological Sciences PART II The History of Big Bangism’s Triumph: A Comedy of Errors Beginning just before the Einstein Revolution was launched by his 1905 Special Relativity paper, let’s weave into the woof and warp of modern cosmology (cosmogony) some of the theoretical input that has brought us to the present day scene wherein the Big Bang Paradigm still rules the roost after some thirty-five years Some insight into the role of several of the players in this almost comical coming and going of theories involves the contributions of Lorentz Einstein de Sitter LeMaitre Eddington Freundlich Freidmann Hubble Born Heisenberg Bethe Gamow Hoyle Penzias Wickramasinghe Sagan and Thornhill HENDRICK LORENTZ Dutch physicist Hendrick Lorentz attempted an explanation that would counteract the Michelson-Morley interferometer results of the 1880’s. Those results consistently showed no movement of the Earth around the sun. Hendrick’s "solution" was to say that the Earth’s speed through the aether in space caused the interferometer arm that was pointed in the direction of the alleged orbit to get shorter ! The Irish physicist FitzGerald had the same idea earlier and called it the "FitzGerald Contraction"...which turned out to be the "FitzGerald Expansion".... Eddingtonto his creditcompared these "solutions" with "...the adventures of Gulliver in Lilliputland and Alice’s adventures in Wonderland".
