Center Of Research In Astronomy, Astrophysics, And Geophysics
The Algiers Observatory was built in the late 19th century in the Algiers suburb of Bouzaréah, Algeria, North Africa. It participated in the Astrographic Catalogue project, taking the zone between -2 and +4 degrees to expose 1,260 plates between the years 1891 and 1911. At the tail end of that time, the director of the installation was François Gonnessiat. It is now known as the Centre de Recherche en Astronomie Astrophysique et Géophysique (CRAAG), where it combines astronomy with work in astrophysics, and geophysical research, including the monitoring of earthquakes.

Joanny-Philippe Lagrula
Joanny-Philippe Lagrula (1870–1941) was a French astronomer. He was sometimes referred to as Philippe Lagrula. In 1901, he wrote his thesis at the University of Lyon. At the time, occultations of the Pleiades by the Moon were important for measuring the correspondence of the Moon's actual position with that predicted by theory. He worked at the Observatory of Lyon, France. On August 1, 1906, he became director of the Quito Astronomical Observatory for a few years. He then worked at Nice Observatory until 1924, when he joined the staff of Algiers Observatory. He was director of Algiers Observatory from 1931 to 1938, replacing François Gonnessiat who retired. His career path mirrored that of Gonnessiat, who had also worked at Lyon, and at the observatories in Quito Quito (; ), officially San Francisco de Quito, is the capital city, capital and second-largest city of Ecuador, with an estimated population of 2.8 million in its metropolitan area.

Buildings And Structures Completed In The 19th Century
A building or edifice is an enclosed structure with a roof, walls and windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much artistic expression. In recent years, interest in sustainable planning and building pract ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Astronomical Observatories
This is a partial list of astronomical observatories ordered by name, along with initial dates of operation (where an accurate date is available) and location. The list also includes a final year of operation for many observatories that are no longer in operation. While other sciences, such as volcanology and meteorology, also use facilities called observatories for research and observations, this list is limited to observatories that are used to observe celestial objects. Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Many modern telescopes and observatories are located in space to observe astronomical objects in wavelengths of the electromagnetic spectrum that cannot penetrate the Earth's atmosphere (such as ultraviolet radiation, X-rays, and gamma rays) and are thus impossible to observe using ground-based telescopes. Being above the atmosphere, these space observatories can also avoid the effects ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Odette Bancilhon
Odette Bancilhon (22 September 1908 – 1998) was a French astronomer. She is best known for her work during the 1930s and 1940s at the Algiers Observatory, in Algeria, North Africa, where she discovered 1333 Cevenola, a stony Eunomian asteroid from the main-belt. Life and work Bancilhon was a graduate in science and she served as a meteorological assistant in Algiers for one year beginning 1 December 1932. On 7 December 1933, she was appointed as Alfred Schmitt's replacement while he performed his military service. In that capacity, in 1934, she discovered the asteroid (1333) Cevenola. (All of her publications at that time were signed ''O. Bancilhon'', a practice of her profession.) She was named an assistant on 1 November 1937. She married her colleague Alfred Schmitt in Algiers on 12 September 1942, and became known professionally as ''O. Schmitt-Bancilhon''. She and her husband were transferred to the Strasbourg Observatory in France on 1 January 1950, and she worked the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Boyer (astronomer)
Louis Boyer (1901–1999) was a French astronomer who worked at the Algiers Observatory, North Africa, where he discovered 40 asteroids between 1930 and 1952. In the 1950s and 1960s. he worked on identifications of small Solar System bodies at Nice Observatory in southeastern France. The asteroid 1215 Boyer, discovered by his colleague Alfred Schmitt at Algiers in 1932, was named after him. In turn Boyer named the 1617 Alschmitt asteroid in honor of Schmitt. Boyer also named 1713 Bancilhon after Odette Bancilhon his colleague and wife of astronomer Alfred Schmitt.

Guy Reiss
Guy Reiss (1904–1964) was a French astronomer and discoverer of five asteroids, who worked at the Algiers Observatory in Algiers, North Africa, during the 1930s and later at the Nice Observatory in southeastern France. Among his discoveries made between 1931 and 1935 at Algiers, he named the minor planets 1237 Geneviève, 1300 Marcelle and 1376 Michelle after his three daughters. His first discovery, 1213 Algeria, was named in honour of the North African country, location of the discovering observatory, and a French colony at the time. The asteroid 1299 Mertona was named after English astronomer Gerald Merton, who became president of the British Astronomical Association in the 1950s. In 1935, he received the Damoiseau-Prize together with André Patry from the French Academy of Sciences The French Academy of Sciences (, ) is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scien ...

Frédéric Sy
Frédéric Sy (1861-1917) was a French astronomer and a discoverer of minor planets. He worked at the Paris Observatory from 1879 to 1887, and as the assistant astronomer at the Algiers Observatory, North Africa, from 1887 to 1918.

Sy was responsible for the discovery and naming of two asteroids, 858 El Djezaïr and 859 Bouzaréah. The names were drawn from locations near the discovering Algiers Observatory. He was awarded the Valz Prize ''(Prix Valz)'' in 1919 by the French Academy of Sciences. The asteroid 1714 Sy was named after him in 1951.

Benjamin Jekhowsky
Benjamin Jekhowsky (; born 1881 in Saint-Petersburg, Russia – died in 1975, Encausse-les-Thermes,France) was a Russian-French astronomer, born in Saint-Petersburg in a noble family of a Russian railroad official. After attending Moscow University, he worked at the Paris Observatory beginning in 1912. Later he worked at the Algiers Observatory (at the time, Algeria was a colony of France), where he became known as a specialist in celestial mechanics. After 1934, he appears to have begun signing scientific articles as Benjamin de Jekhowsky. The Minor Planet Center credits his discoveries under the name "B. Jekhovsky" (with a ''v''). In modern English transliteration, his name would be written as Zhekhovskii or Zhekhovsky. He discovered 12 numbered minor planet According to the International Astronomical Union (IAU), a minor planet is an astronomical object in direct orbit around the Sun that is exclusively classified as neither a planet nor a comet.
