Conrad Mauter (1742-1810)
Conrad Mauter was born in Germany in 1742 and emigrated to Paris in 1765, where he was registered as "ouvrier libre" from 1768 on. In 1787 Mauter married Charlotte Foureau Bliss, the daughter of master cabinet maker Louis Foureau, who was renowned for his lacquered pieces of furniture.
Mauter began in the late 1770s to produce a large number of luxury as well as everyday pieces of furniture for the Parisian society and the French nobility; he mainly built bureaus, escritoires, bureau-plats, bonheurs du jour, libraries, guéridons, salon tables, gambling tables and clock cases. Amongst his illustrious clientele were the Comte d'Artois (later King Charles X), who ordered a large number of pieces for his residences Chateau de Bagatelle and Palais du Temple. Mauter even managed to continue creating outstanding pieces of furniture of exquisite quality during the terrors of the French Revolution.

Antoine Thiout (1692 - 1767)
Antoine Thiout the Elder (known as "l'Aîné") was a French clockmaker. His plates describe clock and watch mechanisms which were often used in 18th century timepieces: for example a verge escapement powered by a spring encased in a barrel, and a regulation based on a cone-shaped fusee.

Thiout received his master’s degree in 1724, most likely though recommendation by the Trinity Hospital. He held the positions of Garde-Visiteur (1742-1745), Horloger de S.M.C. la reine douairière d'Espagne, authorized candidate as of April 18, 1740 for Horloger Ordinaire du Duc d'Orléans with Jean Godefroy (confirmed in 1752).
Certainly a gifted watchmaker, Thiout presented a number of inventions to the Académie des Sciences; most important were his large clocks (1724 and 1726) and his marine clocks. In 1741 he founded a society in partnership with Gallon so that he could publish his impoertant paper "Traité d'Horlogerie", a treatise on clockmaking which was widely read in its time; it was a formidable study which might easily be regarded as the first modern book of its kind. The society dissolved in 1749.
The reputation Thiout gained from his clocks and astronomical clocks brought him a wealthy and important clientele. He worked for several "marchands-merciers" such as N. Gérard and F. Damault and used cases by G. Coulon, A. Foullet, J.J. de Saint-Germain and others; Thiout produced over 30 clocks per year, of which the last one bore the number 1320.
Amongst his customers were Crozat de Thiers, de la Noë, Angrand de Fonpertuis, the Countesses de Sandwich, de Listernois, the Marquesses de Ruffec, de Béringhem, de Crussol, de Montpellier, de Argenson, de Souvré, the Dukes d'Aumont, de Boutteville, d'Olonne, the Duchess de Ruffec, the Princes de Grimberghen and de Conti.
