# Société astronomique de France

The Société astronomique de France (SAF; French:), the French astronomical society, is a non-profit association in the public interest organized under French law (Association loi de 1901). Founded by astronomer Camille Flammarion in 1887, its purpose is to promote the development and practice of astronomy.

## History

SAF was established by Camille Flammarion and a group of 11 persons on 28 January 1887 in Flammarion's apartment at 16 rue Cassini, 75014 Paris, close to the Paris Observatory. Open to all, SAF includes both professional and amateur astronomers as members, from France and abroad.
Its objective was defined at the time of its establishment as: "A Society is founded with the aim to bring together people involved practically or theoretically in Astronomy, or who are interested in the development of this Science and the extension of its influence for the illumination of minds. Its efforts shall support the increase and extension of this Science, as well as to facilitating ways and means for those who wish to undertake astronomical studies. All friends of the Science and Progress are invited for its composition and development."
On 4 April 1887, the headquarters was established at the Hôtel des Sociétés Savantes, 28 rue Serpente, in the 6th arrondissement of Paris. The society built an observatory on the top floor of the building for its members use that operated from 1890–1968 (Observatory of the rue Serpente). On 17 October 1966, the headquarters moved to the Maison de la Chimie at 28 rue Saint-Dominique, Paris 75007. Since 1974, the headquarters has been located at 3, rue Beethoven, Paris 75016.
To date, the Society has had 49 presidents comprising many illustrious persons in astronomy and related fields.
