Wildenstein Institute
The Wildenstein Institute was a French art institute that published "catalogues raisonnés" and scholarly inventories. History. The Institute was founded in 1970 by Daniel Wildenstein as the "Fondation Wildenstein", and it was renamed the Wildenstein Institute in 1990. It was an offshoot of the art dealing company (Wildenstein & Co.) owned by the Wildenstein family for five generations. Until 2017, it housed the historic documents and photographic archives assembled by Nathan Wildenstein (the company founder) and his son Georges, which have been added to by subsequent generations. Daniel Wildenstein established the Wildenstein Index Number used by the Institute to  identify paintings. It published catalogues raisonnés and scholarly inventories of impressionists such as Monet, and other modern artists such as Gauguin. It described itself as a center for research in art history. It was headed by Guy Wildenstein. In 2017, the Wildenstein Institute gifted its entire archive and the rights to all of its publications to the Wildenstein Plattner Institute, Inc., a non-profit art research foundation based in the U.S. and founded by Guy Wildenstein and the Hasso Plattner Foundation. Controversy. The Institute published a Monet "catalogue raisonné," which is regarded as the definitive, scholarly compendium of Monet paintings . Acceptance of a Monet by the Institute significantly increased the commercial value of a painting. The Institute controversially refused to authenticate "Bords de la Seine à Argenteuil" after an investigation by Fiona Bruce (a journalist) and Philip Mould (an art dealer and historian) in the BBC television programme "Fake or Fortune?", which first aired on 19 June 2011. The Institute has since been featured again on the programme, variously accepting and rejecting the team's efforts. Another controversial finding featured on "Fake or Fortune?," first aired July 2015, involved a painting purported to be by Pierre-Auguste Renoir held at  Picton Castle, Wales. The Bernheim-Jeune is one of several sources that established provenance for the "Picton Renoir." The BBC investigators unearthed several lines of authenticity, including additional levels of provenance with photographic records of sale and forensically matching pigments and canvas to Renoir. The Bernheim-Jeune geune Gallery had approved the painting as genuine and have included it in Renoir's "catalogue raisonné". The Wildenstein Institute declined to accept the painting citing insufficient evidence.   In 2011, a police raid discovered and seized 30 paintings valued at tens of millions of pounds from the Institute's Paris headquarters (see: Guy  Wildenstein#Criticism).
