The Argentine National Observatory, today the Astronomical Observatory of Córdoba, was founded on 24 October 1871, by Argentine president Domingo F. Sarmiento and the North American astronomer Benjamin Apthorp Gould.
History
Its creation was the beginning of astronomical studies in Argentina. When President Domingo F. Sarmiento was representing his country in the United States, he had the opportunity to meet pioneering astronomer Benjamin Apthorp Gould, who was very interested in traveling to Argentina in order to study the stellar south hemisphere.
Once Sarmiento was installed as President of Argentina, he Gould to travel to Argentina, in 1869, to provide his full support to organize an observatory. Gould arrived in Buenos Aires in 1870. The same night of the inauguration of the Astronomical Observatory of Córdoba, Gould began with the naked eye, and later with the aid of small binoculars, a map of the southern sky, recording more than 7000 stars, which was published under the name of Uranometría Argentina. He remained as director of the observatory until 1885, when he returned to the United States.
The first stellar photographs in the world – hundreds of sheets of open star clusters – were taken at this observatory. This helped to determine the exact position of each star. Gould published the results in the Catálogo de zonas estelares (1884), the first systematic and large-scale astronomy book, including more than 70,000 stars of the southern hemisphere, and the Argentinian General Catalog, which contains about 35,000 stars. The Catálogo de zonas estelares was republished in 1897 under the title Fotografías Cordobesas.
Bosque Alegre Astrophysical Station
The Bosque Alegre Astrophysics Station was integral to the development of Argentine and Latin American Astrophysics. For example, the famous Atlas of Austral Galaxies by J. L. Sersic.
The Great Reflector was the concept of the director of the Argentine National Observatory, Charles Dillon Perrine, who assumed the directorship in 1909. He proposed to the National Government the construction of the 1.5-meter diameter telescope, equal to the largest in the world at that time. The National Government granted the Observatory the necessary funds in 1912.
The mount and dome were contracted to Warner and Swasey of Cleveland, USA. The glass block for the mirror was ordered from Saint Gobain of France.
Due to the high price of figuring the glass into a mirror by Ritchey (USA), Perrine decided to do the work at the observatory itself in a purpose-built optics laboratory. This experience put Argentina at the forefront in this field.
The death in 1915 of the technician, James Mulvey, the First World War, and the rebuilding of the Observatory in the city of Córdoba significantly delayed the project.
In 1936, Perrine retired, having selected the site, constructed the station buildings, and assembled the telescope mount, but the mirror was not yet complete. F. Aguilar and JJ Nissen, director of the National Observatory, intervened and the mirror was sent for completion to the Fecker optician in the US. At that time, the telescope was the third largest in the world. The first Argentine astrophysicist Enrique Gaviola went to the US in 1939 to receive the mirror. Sadly, Fecker, even with it's well-known expertise, could not complete the mirror. Gaviola took control of the configuration (shaping and polishing) and completed it.
Finally, on July 5, 1942, after 33 years of work, the Astrophysical Station was inaugurated. “This Astrophysical Station was born in the optimistic and courageous mind of Charles Dillon Perrine, director of the Cordoba Observatory from 1909 to 1936. Perrine dedicated the best energies of many years of his life to the realization in the matter of his daring dream. He had triumphs and defeats, successes and failures. " Words by Enrique Gaviola, inauguration speech of the Bosque Alegre Astrophysical Station, July 5, 1942.[1]
