Georgios Konstantinos Vouris

Georgios Konstantinos Vouris (Greek: Γεώργιος Κωνσταντίνου Βούρης; (1802–1860) aka Georg Konstantin Bouris was a Greek astronomer, physicist, mathematician, author, and professor. He was a pioneer in 19th-century Greek astronomy. Vouris lobbied tirelessly to create an astronomical observatory in Athens. He was the first director of the National Observatory of Athens. It was completed in 1846. Greece reconnected with its Astronomical roots. It was the first time since antiquity that a country named Greece played a significant role in Astronomy. He was the first author to publish a university textbook in the field of mathematics since the inception of the new country.

He was born in Vienna to Greek parents. He studied astronomy and mathematics with some of the most important scientists of the time namely Andreas von Ettingshausen and Joseph Johann von Littrow. He did significant research in the fields of astrophysics, astronomy, geodesy, meteorology, number theory, calculus, and probability theory. He moved to Greece and stayed in the country for sixteen years before moving back to Vienna where he lived out the rest of his life. He played a significant role in the founding of the physics and mathematics department at the University of Athens. He did significant research on the elliptical orbital calculations of Biela's Comet. He died at the age of 57 on 16 July 1860, in Vienna. He is buried in the city.

He was born in Vienna, Austria. His father was an entrepreneur. He was from Ioannina and his mother was from Macedonia. His father was Greek and enthusiastic about his heritage. Georgios attended school in Vienna. He enrolled at the University of Vienna in 1820. He was eighteen years old. He initially studied philosophy and law. He earned a scholarship due to his exceptional performance as a student. He was unhappy with philosophy and law and pursued astronomy and mathematics instead. He was taught by Austrian scientist and astronomer Joseph Johann von Littrow. He was also affiliated with Austrian mathematician and physicist Andreas von Ettingshausen. He interacted with some of the most brilliant minds of the Austrian scientific community at the time.

Georgios eventually became a teacher at the Greek school in Vienna from 1826 to 1836. He continued his studies at the Vienna Observatory under the supervision of Joseph Johann von Littrow. He was his doctoral student. In 1832 Georgios published Elliptical orbit calculation of Biela's Comet from 96 observations of the year 1832 (Elliptische bahnbere chung des Biela'schen cometen aus 96 beobachtungen des Jahres 1832). His paper was a comprehensive overview of the elliptical orbital calculations of Biela's Comet. Georgios eventually decided to return to Greece. He initially worked as a translator for the Austrian embassy. The University of Athens was founded in 1837 and he became a professor of astronomy, physics, and mathematics. Georgios also extensively contributed to meteorological observation since 1839. He published a book entitled Meteorological Observations performed in Athens from 1 November 1839 until 30 June 1842 in Athens around 1843. He was profound of the field of astronomy.

He lobbied to create the National Observatory of Athens. He convinced Greek-Austrian entrepreneur and banker Georgios Sinas to fund the massive observatory. When King Otto learned of the generosity he awarded Georgios Sinas's son the Order of the Redeemer. The King also chose the architects for the building under Georgio's supervision. He chose Eduard Schaubert and Theophil Hansen.

Vouris was responsible for selecting and purchasing the correct instruments for the newly founded Observatory. The instruments he chose were a refracting telescope 158 mm in diameter. It featured 6.2" (15.8-cm, 250 cm focal length, f/15) Plößl of Vienna. It was created by Simon Plössl. The second telescope was created by Christoph Starke of Vienna. He worked with optics by Fraunhofer of Munich. It was a meridional telescope 3.7" large (94mm, f/15, diameter 1m). Vouris also purchased two pendulums and a timer. Five small telescopes and a complete line of meteorological equipment. They were the most advanced scientific instruments of the time.

The foundation ceremony was on 26 June 1842. In a notable speech Georgios discussed Meton of Athens and his astronomical observatory that was in the same city over 2200 years before. The observatory was fully operational by 1846 and Georgios was the first director. He continued his scientific work in the field of astrophysics, astronomy, and geodesy. His articles were periodically published in Astronomische Nachrichten. He became internationally renowned in the field of astronomy.

The astronomer also did not publish several works. Some of the works included a catalog for the complete determination of 1000 stars peculiar to Greece and the position of the Athens Observatory. Georgios continued his scientific work. He determined the geographic coordinates of the Observatory, which formed the basis for the mapping of Greece. He also published a five-volume, complete system of mathematics under the title Mathematical Series. He did significant research on the movement of Sirius, Neptune, and Mars. He made specific observations of Mars with the Athens Meridian Circle. His research was used by American astronomer James Melville Gilliss.
