Daniel Wildenstein

Wildenstein's grandfather, Nathan Wildenstein, established an art dealership on the Rue La Boétie in Paris after fleeing his native Alsace during the Franco-Prussian War of 1870/71.

He opened a New York gallery in 1903 and one in London in 1925.

The Wildensteins gained a reputation as shrewd businessmen, stockpiling works to maximise their profits when released onto the market.

Nathan built a huge inventory of European Old Master paintings, sculpture, drawings, furniture and decorative objects, to which Daniel's father, Georges, added Impressionist and Postimpressionist works.

Daniel Leopold Wildenstein (11 September 1917 – 23 October 2001) was a French art dealer, historian and owner-breeder of thoroughbred and standardbred race horses.

He was the third member of the family to preside over Wildenstein & Co., one of the most successful and influential art-dealerships of the 20th century.

He was once described as "probably the richest and most powerful art dealer on earth".

Wildenstein was born in Verrières-le-Buisson, Essonne, just outside Paris.

He had already acted as Group Secretary of the French Pavilion at the World's Fair in 1937 and as exhibitions director at the Chaalis museum and its related Jacquemart-Andre Museum.

He was educated at Cours Hattemer and at the University of Paris, graduating in 1938 and going on to study at the École du Louvre.

In 1940 Daniel Wildenstein went to New York to work for the family firm.

They claimed that eight illuminated manuscripts, dating from the 15th, 16th and 17th centuries and now in the possession of Wildenstein & Co, had been looted by the Nazis in 1940.

The Wildensteins asserted that the books were owned legitimately before the war, that they had been seized from their family safe in October 1940, and that they had then been recovered after the liberation of France.

Daniel Wildenstein suggested that inventory markings on the manuscripts apparently connecting them to the Kann collection were of no significance and suggested that claims to ownership made after so long an interval of time had no validity.

He took over the running of Wildenstein & Co.'s Paris and New York branches in 1959 and those in London and Buenos Aires in 1963, the year his father died.

Wildenstein & Co reopened in Paris after the Second World War but they ended their operations there in the early 1960s after the French minister of culture, Andre Malraux, publicly accused Georges Wildenstein of bribing a ministry official to authorize the export and sale abroad of Georges de La Tour's painting The Fortune Teller.

The case never went to court and Daniel Wildenstein subsequently accused Malraux of being motivated by malice.

More recently Wildenstein & Co has become embroiled in a number of controversies connected with the Nazi confiscation of art works during the Second World War, and with the nature of Georges Wildenstein's relationship with the German regime at that time.

He acted as editor-in-chief of the Gazette des Beaux-Arts from 1963 and in 1971 was elected a member of the Académie des Beaux-Arts.

A gallery in Tokyo was added in the early 1970s.

As an art dealer Wildenstein was phenomenally successful.

His five-volume catalogue raisonné of the work of Claude Monet was published between 1976 and 1992.

His two-volumes on Édouard Manet appeared in 1976 and 1977, those on Gustave Courbet in 1977 and 1977, and a book on Paul Gauguin in 2001.

In 1978 Wildenstein & Co's New York storeroom included 20 pictures by Renoir, 25 Courbets, 10 Van Goghs, 10 Cézannes, 10 Gauguins, 2 Botticellis, 8 Rembrandts, 8 Rubens, 9 El Grecos and 5 Tintorettos among a total inventory of 10,000 paintings.

The secrecy attached to these holdings led to a great deal of interest and speculation in the art world.

Although he officially retired in 1990, Wildenstein is reported to have maintained a close control over the running of the business.

The number of Wildenstein galleries around the world shrank in his later years until it contained only two: Wildenstein & Co. and PaceWildenstein, both in New York.

PaceWildenstein was established in 1993 as a joint venture with the Pace Gallery to deal in contemporary art.

In 1997 the Wildenstein family was sued in New York by the heirs of Alphonse Kann, a prominent Jewish art collector.

A 1998 profile of the family in Vanity Fair magazine asserted that his wealth was estimated at more than $5 billion.

"His fortune," the magazine stated, "was the only one of that magnitude ever made in the art market."

Like his father, Daniel Wildenstein established a reputation as a scholar and art historian.

He revised and enlarged the catalogues published by his father and began work on his own projects, investing in the acquisition of archival material and establishing the Wildenstein Institute to issue catalogues raisonné which became the authority for authenticating the works of major French artists.

In 1999 Wildenstein published a series of his interviews entitled Marchand d’Art.

In May 2000 the Wildensteins lost a court case they had brought in Paris against the art historian Héctor Feliciano, whose book, The Lost Museum: The Nazi Conspiracy to Steal the World's Greatest Works of Art, suggested that although Georges Wildenstein had fled France for America in 1941, the business had continued to trade profitably with the Nazis.

Daniel Wildenstein's sons sued for defamation but lost the case.

The collaboration came to an end in 2010.

In June 2011 Daniel's son, Guy Wildenstein, was charged by the French authorities with concealing art that had been reported as missing or stolen.

He first specialised in 18th-century French painting and sculpture, later expanding to Italian, Dutch, Flemish and Spanish art.

Although he had been working in a tailor's shop when he began to trade in art he proved extremely successful, selling to European collectors such as Edmond James de Rothschild and later to Americans such as J. P. Morgan, Henry Clay Frick, and to the Kress, Rockefeller, and Mellon families.
