Was a Danish astronomer who in 1676 made the first quantitative measurements of the speed of light.

Was a Danish astronomer who in 1676 made the first quantitative measurements of the speed of light. In scientific literature alternative spellings, such as "Roemer", "Römer", and "Romer", are common.In 1681, Rømer returned to Denmark and was appointed professor of astronomy at the University of Copenhagen, and the same year he married Anne Marie Bartholin, the daughter of Rasmus Bartholin. He was active also as an observer, both at the University Observatory at Rundetårn and in his home, using improved instruments of his own construction. Unfortunately, his observations have not survived: they were lost in the great Copenhagen Fire of 1728. However, a former assistant (and later an astronomer in his own right), Peder Horrebow, loyally described and wrote about Rømer's observations.

Is a renowned Danish statistician, who has contributed to many area of the statistical science. He became interested in statistics when, as a student of actuarial mathematics, he worked part-time at the Department of Biostatistics of the Danish State Serum Institute. He graduated from the University of Aarhus (Denmark), where he has spent most of his academic life, and where he became professor of statistics in 1973.

Was a Czech-American Jewish mathematician.She worked first in algebraic number theory, with a doctorate at the University of Vienna supervised by Philipp Furtwängler. During that time in Vienna she also attended the meetings of the Vienna Circle. Later, she started to use matrices to analyze vibrations of airplanes during World War II, at the National Physical Laboratory in the United Kingdom. She became the torchbearer for matrix theory.

Was an American astronomer best known for his work as a stellar spectroscopist.Wilson showed an interest in physics at an early age. He studied astronomy and physics at the University of California, Berkeley and wrote his first scientific paper in 1932 on the subject of the speed of light. He received his PhD from the California Institute of Technology in 1934.Wilson was a staff member of Mount Wilson Observatory for most of his research career where he studied stellar chromospheres. He was the first scientist to discover activity cycles, similar to the solar 11-year sunspot cycle, in other stars. In collaboration with Vainu Bappu he also showed that there was a correlation between the width of the Ca II lines in stellar spectra and the star's luminosity, the Wilson-Bappu Effect.

Was an American astronomer. Some sources incorrectly give his name as Olin Jenck Eggen.He graduated from the University of Wisconsin-Madison in 1940. After serving in World War II in the OSS, he returned to the university and received his Ph.D. in astrophysics in 1948.He became known as one of the best observational astronomers of his time. He is best known for a seminal 1962 paper with Donald Lynden-Bell and Allan Sandage which suggested for the first time that the Galaxy had collapsed out of a gas cloud. He first introduced the now-accepted notion of moving groups of stars.

Was an American economic geographer.By 1912 he took a job with the United States Department of Agriculture, where he would stay for the next thirty years. Baker's work was noticed rather quickly, in part because of his contributions to the Yearbooks from 1915 to 1938, several of which he edited. For the first eighteen years at the USDA he was devoted to studying the geographical aspects of land use. One of his first works, co-authoring Geography of the World's Agriculture (1917) with Vernor Clifford Finch, led him to even wider recognition. Shortly after its publication, Baker returned to the University of Wisconsin-Madison for further graduate study,

A British-born American geneticist and Nobel laureate,[1] credited with the invention of gel electrophoresis in 1950, and the simultaneous discovery, with Mario Capecchi, of the technique of homologous recombination of transgenic DNA with genomic DNA, a much more reliable method of altering animal genomes than previously used, and the technique behind gene targeting and knockout mice.From 1953 to 1960, Smithies worked in the Connaught Medical Research Laboratory, University of Toronto, Canada, due to visa problems,[2] before he could return to his originally planned post as Assistant, Associate and Leon J. Cole and Hilldale Professor of Genetics and Medical Genetics at the University of Wisconsin-Madison, where he worked from 1960 to 1988.[2

Was an American jurist who served on the Supreme Court of the United States from 1902 to 1932. Noted for his long service, his concise and pithy opinions, and his deference to the decisions of elected legislatures, he is one of the most widely cited United States Supreme Court justices in history, particularly for his "clear and present danger" majority opinion in the 1919 case of Schenck v. United States, as well as one of the most influential American common-law judges.

Was a war hero and race car driver. He has been cited as "one of the greatest sportscar racers of all time".On his return to Belgium, Gendebien entered a Veritas sports car in the 1955 Grand Prix des Frontières at Chimay. However, following this race he switched his focus, and teamed up with Fraikin to compete in rally racing using a Jaguar sports car. Together with Pierre Stassen, Gendebien won the sixth running of the Tulip Rally in Zandvoort in April 1954. Their car was an Alfa Romeo. The Gendebien and Fraiken partnership gained the nickname "the eternal bridesmaids", owing to their number of second-place finishes, but after two previous attempts they triumphed in the Liège-Rome-Liège Rally and the Coppa d'Oro delle Dolomiti in 1955, driving a Mercedes-Benz 300SL.

Was a Swedish botanist and taxonomist. He is best known for his taxonomic work and studies into pteridophytes. He attended the University of Uppsala where he studied under Carolus Linnaeus the Younger and received his doctorate in 1781. He first traveled in 1780, to Lapland in the company of several other botanists.[1] From 1783 he sailed for North America and the West Indies, but mostly in the area of Jamaica and Hispaniola, to collect botanical specimens.[2] By 1786 he left for London where he was preparing his flora. There he met Joseph Banks, who was impressed with his knowledge of Botany. He was offered a position with the British East India Company as a travelling physician, but turned it down, and rather returned to Sweden in 1787. However, ten years later he would propose to the Swedish Academy of Sciences the idea of a permanent travel grant,

Was a Portuguese geographer and historian.Among his publications one specific book stands out: Portugal, o Mediterrâneo e o Atlântico (1945). This is one of the cornerstones in his career, as he develops a detailed study on Portugal's "double nature", or in other words, "a country which is Atlantic by location but mostly Mediterranean in culture". Yet, this book had a wide impact, since Ribeiro deepens in the concepts of Atlantic Europe and Mediterranean Europe, linking central and southern Portugal to the Mediterranean culture and northern Portugal (together with Galicia) to a pan-Atlantic European culture
