The Neuchâtel Observatory, situated in the city of Neuchâtel, was founded in 1858 by the Public Economy Department of the canton of Neuchâtel. Under its first director, Adolphe Hirsch, the astronomical observatory conducted clock calibrations based on astronomical observations of the rotation of the Earth.
