International audience; Rédigé par Camille Mestdagh (trad. Jennifer Donnelly)-21/03/2022 Collectionneurs, collecteurs et marchands d'art asiatique en France 1700-1939 Family History: From Dealers to Collectors Originally from Burgundy but established in Paris, on rue du Faubourg Saint-Honoré, Jean Beurdeley (1771-1853) founded a shop selling curiosities around 1817, which was taken over and run by his son Louis-Auguste-Alfred Beurdeley (1808-1882), then his grandson Alfred-Emmanuel-Louis Beurdeley (1847-1919). From the outset, Jean was associated with trade in furniture and secondhand goods, but it was his son Alfred Beurdeley (known as "Beurdeley père") who considerably developed their activity. Under the Second Empire, Beurdeley père became one of the most important dealers in curiosities and works of art in the capital. Under the July Monarchy, his shop was moved to the Pavillon de Hanovre, at the corner of Boulevard des Italiens, in a building acquired by the family in 1830. The store was thus located in the heart of chic Paris at the time and there one could find a quantity of varied and precious goods: marble statuary, ivories, glassware, antique jewellery, bronze clocks, paintings, chandeliers, furniture in marquetry or lacquer

The ability to construct easily in vitro networks of primary neurons organized with imposed topologies is required for neural tissue engineering as well as for the development of neuronal interfaces with desirable characteristics. However, accumulating evidence suggests that the mechanical properties of the culture matrix can modulate important neuronal functions such as growth, extension, branching and activity. Here we designed robust and reproducible laminin-polylysine grid micropatterns on cell culture substrates that have similar biochemical properties but a 100-fold difference in Young's modulus to investigate the role of the matrix rigidity on the formation and activity of cortical neuronal networks. We found that cell bodies of primary cortical neurons gradually accumulate in circular islands, whereas axonal extensions spread on linear tracks to connect circular islands. Our findings indicate that migration of cortical neurons is enhanced on soft substrates, leading to a faster formation of neuronal networks. Furthermore, the pre-synaptic density was two times higher on stiff substrates and consistently the number of action potentials and miniature synaptic currents was enhanced on stiff substrates. Taken together, our results provide compelling evidence to indicate that matrix stiffness is a key parameter to modulate the growth dynamics, synaptic density and electrophysiological activity of cortical neuronal networks, thus providing useful information on scaffold design for neural tissue engineering.

Présentation de la dynastie Beurdeley

International audience

The Beurdeley dynasty was established in Paris from 1818 to 1895. They were active in the trade of "curiosities" (as antiques were then described) but they also founded a workshop for the manufacture of furniture and gilt bronzes. The study of their business reveals the increasing value devoted to curiosities, the consumption and the circulation of works of art, both antique and modern, the trade and the workshop practices throughout the nineteenth century. The dual activity of dealer and manufacturer is significant and exposes the correlations between the commerce, the development of the taste for old objects following the intense circulation of merchandises triggered by the Revolution, and a modern production built on a system of references appropriating patterns from the 17th and 18th centuries. The market for curiosities developed around dealers, the first to compile knowledge, particularly with catalogs and auctions booming. Later, through the development of their collections, museums encouraged the fad. Selling old and new works of art was not unusual for a dealer but the Beurdeley’s double vocation brings to light the transfer of knowledge from the shop to the workshop and the extent of the influences and practices that occur between trade and commerce, between the old and the new. The workshop analysis reveals an organisation inherited from the guilds era, before entering the age of industry. It reflects the transition between the appropriation of the Ancien régime heritage and the establishment of a modern structure following the aim for the development of a luxury industry whose international influence is growing, stimulated by the great exhibitions. Established in the heart of the Parisian market, the Beurdeley business gained a strong reputation and by the nature of their trade and their production they participated in the formation of a French international style, based on the appropriation of the eighteenth century and promoted by the cosmopolitan elites from the 1850s well into the 20th century., Les Beurdeley forment une dynastie parisienne en activité de 1818 à 1895, qui s’est consacrée au commerce d’objets anciens désignés comme «curiosités» et à la création d’un atelier de fabrication de meubles et de bronzes dorés. Leur histoire constitue un témoignage sur la valorisation, la conception, la consommation et la circulation des objets d’art, anciens et modernes, tout au long du XIXe siècle. La double occupation de marchand et de fabricant est originale et dévoile les corrélations entre le développement du commerce, l’accroissement des valeurs dévolues aux objets d’ameublement anciens suite à l’intense circulation de marchandises enclenchée à la Révolution, et une œuvre moderne qui s’appuie sur un réseau de références ornementales, empruntant aux XVIIe et XVIIIe siècles. Le marché des curiosités se construit autour des marchands qui échafaudent une connaissance, notamment par le biais des catalogues et des ventes aux enchères en plein essor. Le relai est ensuite assuré par les collections muséales en formation qui encouragent cette valorisation. Nombreux sont les marchands qui associent marchandises anciennes et modernes mais le cas des Beurdeley permet d’analyser directement le transfert de la connaissance de la boutique à l’atelier et l’étendue des influences et des pratiques qui font le lien entre le commerce et l’œuvre, entre l’ancien et le neuf. L’étude de l’atelier révèle la continuation d’une organisation établie au temps des corporations, avant d’entrer dans l’ère des grandes entreprises. Elle reflète la transition entre l’appropriation des héritages de l’ancien régime et la mise en place d’un fonctionnement représentatif des aspirations contemporaines où les arts décoratifs forment un pilier de l’industrie du luxe dont l’influence internationale est grandissante, notamment grâce aux expositions universelles. Installés au cœur du marché parisien, ils ont bénéficié d’une haute réputation et par la nature de leur commerce comme par leur œuvre ils ont participé à l’affirmation d’un style français international. Un style fondé sur une appropriation du XVIIIe siècle diffusé par les élites cosmopolites dès le Second Empire et au-delà de la Belle Epoque.
