Lepaute Horloger du Roi à Paris
This is the signature of the brothers Jean-André Lepaute (1720-1789) and Jean-Baptiste Lepaute (1727-1802), remarkable clockmakers born in Thonne-la-Long in Lorraine who were both horlogers du Roi.
Jean-André came to Paris as a young man and was joined by his brother in 1747. The Lepaute enterprise, founded informally in 1750, was formally incorporated in 1758. Jean-André, who was received as a maître by the corporation des horlogers in 1759, was lodged first in the Palais du Luxembourg and then, in 1756, in the Galeries du Louvre.
Jean-André Lepaute wrote a horological treatise (Traité d'Horlogerie), published in Paris in 1755. Another volume, entitled Description de plusieurs ouvrages d'horlogerie (A Description of several horological pieces) appeared in 1764.
In 1748 he married the mathematician and astronomer Nicole-Reine Etable de la Brière, who among other things predicted the return of Halley’s Comet.
Jean-Baptiste Lepaute, received maître in December 1776, was known for the equation of time clock he constructed for the Paris Hôtel de Ville (1780, destroyed in the fire of 1871) and the clock of the Hôtel des Invalides.
The two brothers worked for the French Garde-Meuble de la Couronne; their clocks were appreciated by the most important connoisseurs of the time, both in France and abroad, such as the Prince Charles de Lorraine and the Queen Louise-Ulrika of Sweden.
Jean-Baptiste took over the workshop when Jean-André retired in 1775.
