The Minute Books of the Bureau des Longitudes for the period 1795-1832 can now be consulted online
The Bureau des Longitudes was founded on 25 June 1795 and still exists today. From its foundation, and until 1854, it maintained the management of the Observatoire de Paris. Its mission was also to improve longitude determination at sea and to form a consultative committee of scientific and technological expertise for the State. In particular, it was charged with calculation of ephemerides and publication of the Connaissance des Temps and the Annuaire du Bureau des Longitudes. In 1877 and 1949 it also published the Annales du Bureau des Longitudes.
The online resource is the outcome of a collaboration between the Bureau des Longitudes, the Library of the Observatoire de Paris and the Laboratoire d'histoire des sciences et de philosophie - Archives Henri Poincaré. It was made possible thanks to a grant from the Ministère de l'Enseignement Supérieur et de la Recherche (programme BSN5-2013) and the support of the Maison des Sciences de l'Homme Lorraine, and thanks too to the skills of the engineers Julien Muller and Pierre Couchet.
