Argelander (1799-1875), Astronomer Friedrich Wilhelm August Argelander was born at the 22nd of March 1799 in Memel critical review of the observations by John Flamsteed (1646-1719), who had published an uncorrected and not levelled summary of his celestial observations from 1676 to 1705 in 1712. This was the base for a posthum published, famous star catalog of 1725, extended in 1728, about 2848 exact fix star positions. This was one of the first star maps after the invention of the telescope. Flamsteed also had introduced a new system for numbering the stars within their constellations, which is in use today, still. - The next larger star catalog was made by Johann Elert Bode (1747-1826) in 1801 named "Uranographia, sive astrorum descriptio", including ca. 17000 stars. "About the Proper Motion of the Solar System" From 1836/7 he began with the first plans on an observatory in Bonn, which should be financed by Friedrich Wilhelm IV. (1795-1861), who became king in 1840 and who arranged a Cologne Dome Festivity in 1842 and a Millennium Celebration of the German Reich in 1843, marking his nationalistic intends. But the Bonn observatory had to wait and was ready in the middle of 1844 and inaugurated in 1845. While the construction time in 1843 Argelander published a catalog of the fixstars visible by the naked eye, where he created a unique method for estimating the brightness of the stars in relation to one another. He called the catalog

    Extractions: Das Thema des Monats März Friedrich Wilhelm Bessel Bessel, Friedrich Wilhelm, * 1784 in Minden, + 1846 in Königsberg. Bessels Vater, ein Justizrat, hatte drei Söhne und sechsTöchter und bemühte sich, seinen Kindern eine gute Ausbildung zuteil werden zu lassen. Friedrich Wilhelm verließ jedoch das Gymnasium aus Abneigung gegen den Lateinunterricht und unterzog sich einer Kaufmannslehre in Bremen. Um sich auf spätere Handelsreisen vorzubereiten, las er Reisebeschreibungen, lernte Englisch und Spanisch, studierte Schiffahrtskunde, Nautik und schließlich Astronomie. Er baute sich ein Fernrohr und machte genaue Orts- und Zeitbestimmungen. Durch Vorträge des Arztes und Liebhaberastronomen Wilhelm Olbers (1758-1840) wurde seine Neigung zur Astronomie verstärkt. Olbers sagte später einmal, er halte es für seine große Leistung, daß er Bessel für die Astronomie gewonnen habe. Bessel berechnete die Bahn des Kometen Halley und schrieb darüber eine Arbeit, die in Zach's Monatskorrespondenz gedruckt wurde. Olbers machte Bessel mit Gauß bekannt und vermittelte ihm 1806 eine Stelle an der Privatsternwarte von Johann Hieronymus Schröter (1745-1816) in Lilienthal bei Bremen. 1810 wurde er von W.v.Humboldt nach Königsberg berufen als Professor der Astronomie und Direktor der neugebauten Sternwarte. Er heiratete die Tochter des Medizinalrates Hagen in Königsberg. Beide hatten einen Sohn (der noch zu Bessels Lebzeiten starb) und drei Töchter. Die älteste von ihnen heiratete Adolf Erman.

Propaganda Short Biography of Friedrich Wilhelm Bessel Life and accomplishments Another major discovery by Bessel was that the two bright stars Sirius and Procyon execute minute motions that could be explained only by assuming that they had invisible companions disturbing their motions. The existence of such bodies, now named Sirius B and Procyon B, was confirmed with more powerful telescopes after Bessel's death. An important share in the discovery of the planet Neptune also belongs to Bessel. In a paper read in 1840, he called attention to exceedingly small irregularities in the orbit of Uranus, which he had observed and concluded were caused by an unknown planet beyond.

    Extractions: of November 1472, at Ravenna. Bessarion was one of the most learned scholars of his time. Besides his translations of Aristotle’s Metaphysics and Xenophon’s Memorabilia, his most important work is a treatise directed against George of Trebizond, a violent Aristotelian, entitled In Cal umni atorem Platonis. Bessarion, though a Platonist, is not so thoroughgoing in his admiratio’-’ as Gemistus Pletho, and rather strives after a reconciliation of the two philosophies. His work, by opening up the relations of Platonism to the main questions of religion, contributed greatly to the extension of speculative thought in the department of theology. His library, which contained a very extensive collection of Greek MSS., was presented by him to the senate of Venice, and formed the nucleus of the famous library of St Mark. See A. M. Bandini, Dr Vita et Rebus Gestis Bessarionis (17~7); H. Vast, Le Cardinal Bessarion (1878); E. Legrand, Bibliographie Hellinique (1885); G. Voigt, Die Wiederbelebung des klassischen Altertu,ns, ii.

    Extractions: Friedrich Wilhelm Bessel . This is a garbled version of the truth: it was his grandfather, Bessel's son-in-law, who changed his own name from "Hagen" to "Bessel-Hagen" to preserve Bessel's name, since the latter had died without leaving any male heirs. Briefly, Erich Bessel-Hagen was born near Berlin on September 12, 1898. He attended the University of Berlin, where he obtained his doctorate under the direction of Felix Klein , helping Klein to finish the editing of his collected works, just prior to his death in 1925. At the same Bessel-Hagen was finishing his habilitation work on elliptic modular functions. In 1927 he moved to the University of Halle, where he worked closely with Helmut Hasse . In 1929 he moved to Bonn where he worked closely with Otto Toeplitz , mainly on research in the history of mathematics. He remained in Bonn until his death on March 29, 1946. Bessel-Hagen had wide-ranging mathematical interests, including calculus of variations, function theory, number theory, mathematical physics and history of mathematics. He is cited by many authors, including such eminent mathematicians as Emmy Noether , for helpful remarks and other informal contributions. Bessel-Hagen was also a gifted philologist with an impressive command of Greek, Latin and Arabic, which he put to good use in his researches on the history of mathematics. He also worked energetically to collect and preserve the correspondence and unpublished works of contemporary mathematicians, such as Klein, Hausdorff, and Toeplitz. Bessel-Hagen was generally regarded by his contemporaries as a very talented mathematician, who unfortunately did not realize his full potential due to his personality traits.

    Extractions: and the Wilhelm-Foerster-Observatory Gottfried Wilhelm Leibniz (1646-1716) arranged with the support of electoress Sophie Charlotte the establishment of a scientific foundation in Berlin/Brandenburg in the year 1700 AD, the "Societaet der Wissenschaften", of which he became the first president. The first astronomer of the foundation became Gottfried Kirch (1639-1710) who did his observations at the private observatory of the privy councillor von Kroseck (see above). Kirch got help from his son Christfried and his wife Maria Margareta (1670-1720), who discovered the Comet of 1702. The building of the private observatory remained until 1905 within the former Berlin district Neu Coelln. Then it was removed in favor for an office building. Under management of the society of sciences at the beginning 18th century the (old) Berlin Observatory was build within the Dorotheen municipal in the Marstall (the royal stable, see above). At January the 15th, 1711 the first meeting of the society took place within the five floor tower at the Letzte Str. (since 1822 Dorotheenstr., 1949-1995 Clara-Zetkin-Str., then Dorotheenstr. again). The society was replaced 1744 by the "Preussische Akademie der Wissenschaften", the prussian academy of sciences, founded by Friedrich II., called Friedrich The Great or The Old Fritz. The astronomical institute relating to the observatory was financed totally by the proceeds of the monopoly for calendar calculation until 1811. In this period among others Johann Bernoulli III. (1744-1807 astronomer and mathematician)
