First European Congress Of Astronomers
The first European congress of astronomers took place in August 1798 at the Gotha Observatory, Seeberg Observatory in Gotha, Germany. It lasted around ten days. Organized by Franz Xaver von Zach, the congress brought together European astronomers to discuss star cataloging, instrumentation, and the adoption of the metric system. A follow-up congress in 1800 led to the formation of the celestial police, an association of astronomers that discovered several minor planets. Organization The Seeberg Observatory, commissioned in 1790 by Franz Xaver von Zach, quickly became a centre of the European astronomical community. Zach corresponded with almost all colleagues in the field, and the observatory he designed was visited often because of its innovative features. At the beginning of 1798, the French astronomer Jérôme Lalande expressed a desire to visit the Seeberg Observatory, where he hoped to meet the Berlin astronomer Johann Elert Bode. Zach sent invitations to astronomy-related ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johann Gottfried Köhler
Johann Gottfried Köhler (15 December 1745 – 19 September 1801) was a German astronomer who discovered a number of nebulae, star clusters, and galaxies. Köhler is best remembered for his discovery of Open Cluster M67, Elliptical Galaxy M59, and Elliptical Galaxy M60. The latter two were discovered on the same day, 11 April 1779. He worked with the noted astronomer Johann Elert Bode, who refined and published Köhler's proposal for the symbol of Uranus. From 1784 he was the director of Mathematisch-Physikalischer Salon The Mathematisch-Physikalischer Salon (, ''Royal Cabinet of Mathematical and Physical Instruments'') in Dresden, Germany, is a museum of historic clocks and scientific instruments.

Georg Simon Klügel
Georg Simon Klügel (August 19, 1739 – August 4, 1812) was a German mathematician and physicist. He was born in Hamburg, and in 1760 went to the University of Göttingen where he initially studied theology before switching to mathematics. Georg Christoph Lichtenberg was a fellow student. His doctoral thesis ''Conatuum praecipuorum theoriam parallelarum demonstrandi recensio'', published in 1763 with Abraham Gotthelf Kästner as doctoral advisor, was a study of 30 attempted proofs of the parallel postulate. It was influential at the time and much cited. Klügel edited the ''Hannöversche Magazin'' for 2 years from 1766, before becoming professor of mathematics at the University of Helmstedt. In 1788 he succeeded Wenzeslaus Johann Gustav Karsten to the chair of mathematics and physics at the University of Halle. He died in Halle in 1812. He remained in correspondence with Lichtenberg throughout his career. Klügel made an exceptional contribution to trigonometry, unifying ...

Johann Jakob Huber
Johann Jakob Huber (27 August 1733, Basel – 21 August 1798, Gotha) was a Swiss astronomer. Life and work Huber was the eldest of two sons born to the Basle trader Johann Jakob Huber (1704–1759) and his first wife Anna Maria Winkelblech (1706–1736). He studied at the usual Basle schools. His father had originally envisioned a career for his eldest son similar to his own, but as he showed early on his inclination towards mathematics and astronomy, he allowed him to receive a correspondingly suitable education. Among his university lecturers in his home town of Basle were the mathematicians Daniel Bernoulli and Johann II. Bernoulli. In 1754 Huber was an astronomer at the Royal Greenwich Observatory. From 1754 till 1755 he undertook a scientific sojourn through England. During this trip he wrote on 19 October 1754, in Croydon, an essay on the determination of longitude at sea, containing thoughts on a particular part that a mechanical clock needs to have an escapement with ...
