André-Louis Danjon
André-Louis Danjon (; 6 April 1890 – 21 April 1967) was a French astronomer born in Caen to Louis Dominique Danjon and Marie Justine Binet. Danjon devised a method to measure "earthshine" on the Moon using a telescope in which a prism split the Moon's image into two identical side-by-side images. By adjusting a diaphragm to dim one of the images until the sunlit portion had the same apparent brightness as the earthlit portion on the unadjusted image, he could quantify the diaphragm adjustment, and thus had a real measurement for the brightness of earthshine. He recorded the measurements using his method (now known as the Danjon scale, on which zero equates to a barely visible Moon) from 1925 until the 1950s. Among his notable contributions to astronomy was the design of the impersonal (prismatic) astrolabe based on an earlier prismatic astrolabe developed by François Auguste Claude which is now known as the Danjon astrolabe, which led to an improvement in the accuracy ...

Scientists From Caen
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

Prix Jules Janssen
The Prix Jules Janssen is the highest award of the Société astronomique de France (SAF), the French astronomical society. This annual prize is given to a professional French astronomer or to an astronomer of another nationality in recognition of astronomical work in general, or for services rendered to Astronomy. The first recipient of the prize was Camille Flammarion, the founder of the Société astronomique de France, in 1897. The prize has been continuously awarded since then with the exception of the two World Wars. Non-French recipients have come from various countries including the United States, the United Kingdom, Canada, Switzerland, the Netherlands, Germany, Belgium, Sweden, Italy, Spain, Hungary, India, the former Czechoslovakia, and the former Soviet Union The Soviet Union,. officially the Union of Soviet Socialist Republics.

L'Astronomie (magazine)
''LAstronomie'' () is a monthly astronomy magazine published by the Société astronomique de France (SAF). Sylvain Bouley, the president of SAF, is the publication director and astronomer Fabrice Mottez is the editor-in-chief. History The magazine was established by Camille Flammarion and the first issue, dated 1882, was published on January 1, 1883. After SAF was founded in 1887, a second journal was created, called the ''Bulletin mensuel de la Société Astronomique de France''. The two publications existed in parallel up to 1894. In the December 1894 issue, Flammarion announced in an editorial that ''LAstronomie'' would cease to exist. From January 1895 to December 1910, only the ''Bulletin de la Société Astronomique de France'' was published. Starting from 1912, the ''Bulletin'' was renamed ''LAstronomie'', while preserving the volume numbering of the ''Bulletin''.

Observatoire De Paris
The Paris Observatory (french: Observatoire de Paris ), a research institution of the Paris Sciences et Lettres University, is the foremost astronomical observatory of France, and one of the largest astronomical centers in the world. Its historic building is on the Left Bank of the Seine in central Paris, but most of the staff work on a satellite campus in Meudon, a suburb southwest of Paris. The Paris Observatory was founded in 1667. Construction was completed by the early 1670s and coincided with a major push for increased science, and the founding of the Royal Academy of Sciences. King Louis XIV's minister of finance organized a "scientific powerhouse" to increase understanding of astronomy, maritime navigation, and science in general. Through the centuries the Paris Observatory has continued in support of astronomical activities, and in the 21st century connects multiple sites and organizations, supporting astronomy and science, past and present.
