Gui Rochat

Gui Rochat (Guillaume Frédéric Rochat, born 1933) is an international private art dealer and consultant, dealing primarily in seventeenth- and eighteenth-century French paintings and drawings, working from New York as "Gui Rochat Old Masters". His long experience with four art auction houses, Sotheby's, Phillips, Son & Neale, Butterfields (now Bonhams) and Doyle New York has given him the background for rescuing a number of Old Master paintings from oblivion. He is proud to have Antoine Le Grand Batard de Bourgogne (1421-1504), painted by Rogier van der Weyden as well as by Hans Memling, as a direct ancestor.

Early life and education
Listed in the Who is Who in the East 1986/7, he was born in 1933 on Java, then the Dutch East Indies, grandson of Prof. Guillaume Frédéric Rochat (1876–1965) and son of Dr. Guillaume Frédéric Rochat and attorney-at-law Bertha Rochat. Gui Rochat was educated at the Latin and Greek Gymnasium school in Zwolle, The Netherlands, from 1946 to 1953, after which he entered the Dutch navy in the training program for reserve lieutenant. Following a short unsuccessful spell of being a cadet in the Dutch Naval Academy he entered Groningen University in the Netherlands 1956 as a student in Medicine. This not being a career he desired, his parents who were living then in Iran sent him to the American University of Beirut, Lebanon, where he graduated in 1960 with a major in Experimental Psychology. This enabled him to continue his graduate studies at Indiana University, where he met his late wife Katherine McCollum. They have one child, Corinne Elise Alexandra.

Professional career in the Fine Arts
After completing a training program at Sotheby's New York City, he was sent as the director for the South-East to Houston, Texas, in 1970/71, where he ran Sotheby's gallery in the Galleria Post Oak. He was instrumental in selling several Post-Impressionist paintings which now form part of the Beck and Law Collections in the Houston Museum *. Thereafter he was trained in the Old Master and 19th-Century painting departments at Sotheby's, London, after which he entered their Old Master painting department in New York till 1974. He joined Philips, Son & Neale in 1979 as the Fine Art consultant and became president in 1981 at their New York location, the Rhinelander mansion on Madison Avenue, during which he catalogued the fine art from the estate of Elizabeth Fuller Chapman.

He was given a one-man exhibition of his private collection of European art glass in the New Orleans Museum of Art in 1986 and was invited to write an article on a recently acquired large portrait of Louis XVI, an autograph version of the Versailles portrait by the painter Antoine-François Callet. In 1989 he was appointed director of Fine Arts at Butterfield & Butterfield in San Francisco and became a vice-president in 1990. There he considerably increased the volume of sales and appraised the very important fine art in the Elise S. Haas estate, now in the Museum of Modern Art in San Francisco, which included the famous portrait of his wife in a blue hat by Matisse from 1905, Matisse's portraits of Leo and Sarah Stein and the sculpture "La Négresse Blanche" by Brâncuși. Rochat also catalogued the fine art in the estate of composer Edgard Varèse and Louise Varèse.

Rochat discovered works by such artists as Giorgio de Chirico, Yves Tanguy, Pierre Soulages and Amedeo Modigliani, hidden theretofore in Western collections. In 2005/6 he became Fine Arts consultant at DoyleNewYork, where again he made discoveries such as a rare drawing by Egon Schiele, now in the Neue Galerie museum in New York and an important small panel by Joaquín Sorolla y Bastida, circa 1900 of the beach at San Sébastian, with the image of his wife in the foreground.

Private career in the Fine Arts
Gui Rochat has made some remarkable discoveries of disappeared and unrecognized Old Master paintings and drawings, i.e. European paintings created before circa 1800 during his activities as a private Old Master painting and drawing dealer.

Examples of these are two canvases by the French/Italian master Michele DeSubleay (or Michele Desubleo), both now illustrated in color in the catalogue raisonné of his work, one of which was already recorded as lost, mentioned in his testament (cf Thieme Becker and Milantoni). And an important large oil on paper study for an unknown altar painting of the Martyrdom of Saint Bartholomew by Antoine Rivalz, acquired by the Musée des Augustins in Toulouse, France, also fully illustrated and described in the catalogue raisonné on the artist.

Rochat found a superb pair of red chalk drawings by François Boucher, after a painting by Francesco Solimena, that formed part of the collection of Cardinal Fesch, the uncle of Napoleon, now housed in the cardinal's museum palace in Ajaccio, Corsica. They proved a fact which was not known till then that Boucher on his voyage to Italy had stopped in Venice probably around 1730, where the Solimena work was then still hanging in the Baglioni collection. These drawings are now both in Ajaccio.

The National Gallery of Scotland acquired a rediscovered strong oil sketch of a young woman in profile by the Flemish artist François-Joseph Navez, a pupil of Jacques-Louis David, and a significant and beautiful oil sketch of Achilles presenting the body of Hector to the deceased Patroclus by the French/Flemish artist Joseph-Benoît Suvée, a later and changed version of his work in the Louvre is now in a European private collection and will be included in the forthcoming catalogue raisonne by Drs. Join-Lambert and Leclair. The Montreal Museum of Fine Arts bought in 2008 a significant small oil on copper of the Virgin and Christ by the forerunner of Canadian art, the French monk Frère Luc, who entered a Quebec monastery in the late 17th century.

A more recent discovery is that of a drawing preparatory for an engraving by Claudine Bouzonnet-Stella, the niece of the more famous French artist Jacques Stella, who was a close friend of Nicolas Poussin when both worked in Italy. Stella had bought a beautiful painting by Poussin of Venus giving arms to Aeneas, which is now in the museum in Rouen and on his death it was inherited by Bouzonnet Stella, who was an excellent engraver. This drawing was done by her from the painting and squared for transfer, i.e. for being engraved.

Aside from his interest in French Old Masters, Gui Rochat discovered in New York for a collector a very large and important work by the Dutch master Abraham Bloemaert fully signed and dated 1624, which was offered by Sotheby's New York in a very dirty condition as attributed to Bloemaert's son, a much lesser painter. The signature and date appeared after cleaning of the painting. In the Braith-Mali Museum at Biberach in Germany is now a rediscovered small copper by the German master Johann Heinrich Schönfeld of Alexander offering Campaspe to Apelles. And the Rijksmuseum in Amsterdam acquired a very charming drawing in red chalk of a young woman looking at an engraving, recognized as by the 18th-century Dutch artist Gijsbertus van der Berg.

Also among the most recent discoveries is a small but very fine oil on copper by the baroque French artist Jacques de Létin of Saint Catherine of Alexandria, which is now in the Musee des Beaux-Arts in Troyes, France, and a very rare discovery of "The Calling of Saint James the Greater" by Claude-Guy Hallé (catalogue raisonné on the artist by Nicole Willk-Brocard, 1995, p. 286, number C 42 listed as lost).

Recently was sold to a Paris collection a very fine 'Allegory of Venus with Eros and Anteros' by Charles Poerson (French, 1609–1667), a painting that remained for a long time without a correct attribution though it was sold in a Sotheby Monaco sale in 1994 and stayed till recently in a major Italian collection as  by an unknown but major French seventeenth century painter. It was on loan to the Los Angeles County Museum of Art in 2013.

More recently was discovered a large ‘Penitent Saint Dominic’ now in a major Paris collection, which is described by Robert Fohr in his 2018 magnificent book on Georges de La Tour. He received for this book the Marmottan prize from the Paris Academy of Fine Arts (see the Wikipedia entry for Robert Fohr). Fohr describes the painting as a possible copy from a late work by Georges de La Tour, but it is probably in fact an autograph work.
