[TURGOT (Michel-Étienne)] - BRETEZ (Louis). Map of Paris. S.l. [Paris], s.n. 1734-1739. In-folio bound in full leopard-printed blond calf, spine ribbed and decorated with gilt fleurs-de-lys, gilt fleur-de-lys border and spandrels framing the boards embossed with the arms of the city of Paris, gilt fleur-de-lys border to the edges and another int. fleur-de-lys border, gilt edges (Period binding). Entirely engraved work consisting of 20 double-page plates mounted on mitre and an assembly plan mounted at the head. Plates 18 and 19 are folded together. This is the first edition of Turgot's plan, one of the most beautiful maps of Paris produced from a cavalier perspective. This map is the result of a lengthy cartographic project launched in January 1934 by the City of Paris, which commissioned the draughtsman Louis Bretez, a professor of perspective at the Saint-Luc Academy of Painting. At the instigation of the Marquis Michel-Etienne Turgot, the Paris merchants' representative and State Councillor, the project took shape, and Bretez spent two years surveying every corner of the city to produce a highly accurate survey drawing of the organisation of Paris, which was then engraved with etching and burin. Intended as a showcase for the prestige of the French capital, this plan was published in 1739, after the death of Louis Bretez.

The selection we have the honour of offering at auction highlights a subtle balance between erudition and the art of living. Comprising mainly works from the eighteenth and twentieth centuries, this collection covers more than five centuries of printed production, closely linked to the history of Geneva and the Tronchin family, one of the city's great patrician lineages, now extinct. A number of seventeenth-century titles hark back to the origins of this lineage, notably around the figure of Théodore Tronchin (lot 2567). However, it was in the 18th century, with the acquisition of the Bessinge estate by Jacob Tronchin in 1764, that the collection really took shape. The works, many of which bear the bookplates of Jean Armand Tronchin (1732-1813) and his son Henri (1794-1865), make up a collection faithful to the ideals of the Enlightenment, combining public law, classical humanities, science, travel accounts (lots 2471, 2479, 2554..), major works of 18th-century printing - including the plan of Paris by Turgot (lot 2591) - and rare editions bearing the royal coat of arms, such as those of Madame de Pompadour (lot 2545). At the turn of the 20th century, a new page was turned when Xavier Givaudan (1867-1966), a leading figure in the industrial boom alongside his brother Léon Givaudan (1875-1936) in the fields of synthetic perfume, chemicals and soap, established in Switzerland in 1917, acquired the estate in 1938 after renting it for several years. The library and works have been preserved and in part passed on to his descendants. His brother Léon Givaudan built up a bibliophile collection focusing on Art Deco books, bringing together works sublimated by bindings signed by the great contemporary bookbinders (lots 2606, 2626, 2648, etc.). His library was sold at auction in Paris on 3 June 1988. André Givaudan (1895-1973), Xavier Givaudan's son, also had a particular interest in literature, joining several bibliophile societies and adding a number of modern illustrated books to the collection. All the lots marked in brown in the printed catalogue come from the Tronchin-Givaudan Collection, then by descent to the current owners.
