The Toulouse Observatory (French: Observatoire de Toulouse) is located in Toulouse, France and was established in 1733.[1]

It was founded by l'Académie des Sciences, Inscriptions et Belles-Lettres de Toulouse ("Academy of Science, Inscriptions and the Humanities of Toulouse"). It was moved 1841 and again in 1981.[citation needed]

In 1987, Genevieve Soucail of the Toulouse Observatory and her collaborators presented data of a blue ring-like structure in Abell 370 and proposed a gravitational lensing interpretation[2]

In the 1990s the observatory worked on MEGACAM with several other institutions.[3]


Félix Tisserand was a famous director from 1873 to 1878. He published Recueil d'exercices sur le calcul infinitesimal as well as making several expeditions, including an 1874 trip to Japan. Henri Joseph Anastase Perrotin was Tisserand's assistant astronomer, and they both went to the Paris Observatory in 1878. Tisserand was succeeded by Benjamin Baillaud.
