Question: Almond Blossoms was created to celebreate the son of which Dutch art dealer?
Context: René Gimpel (1881–1945) was a prominent French art dealer of Alsatian Jewish descent who died in 1945 in Neuengamme concentration camp, near Hamburg, Germany.  Friend and patron of living artists and collectors, he was the son of a picture dealer and the brother-in-law of Sir Joseph Duveen.  His witty and acerbic "Journal d'un collectionneur: marchand de tableaux" (1963, revised edition 2011), with a preface by Jean Guéhenno of the Académie française, was translated and published as "Diary of an Art Dealer" (1966), and is a primary source for the contemporary history of modern art and of collecting between the World Wars. Almond Blossoms is from a group of several paintings made in 1888 and 1890 by Vincent van Gogh in Arles and Saint-Rémy, southern France of blossoming almond trees.  Flowering trees were special to van Gogh.  They represented awakening and hope.  He enjoyed them aesthetically and found joy in painting flowering trees.  The works reflect the influence of Impressionism, Divisionism, and Japanese woodcuts. "Almond Blossom" was made to celebrate the birth of his nephew and namesake, son of his brother Theo and sister-in-law Jo. Theodorus "Theo" van Gogh (] ; 1 May 1857 – 25 January 1891) was a Dutch art dealer.  He was the younger brother of Vincent van Gogh, and Theo's unfailing financial and emotional support allowed his brother to devote himself entirely to painting.  Theo died at the age of 33, six months after his brother died at the age of 37. Cornelis Sebille Roos or Cornelis Roos (1754 – 1820) was a Dutch art dealer and inspector of the Nationale Konst-Gallery collection in Huis ten Bosch during the years 1799-1801 Alois Miedl (3 March 1903 - 4 January 1990) was a naturalized Dutch art dealer, originally a German Nazi banker, born in Munich, who had moved to and was mainly active in the Netherlands, involved with the sales of properties stolen from Jews who had fled or had been deported. Robert Christiaan Noortman (5 March 1946 – 14 January 2007) was a Dutch art dealer. Ernst Beyeler (16 July 1921 – 25 February 2010) was a Swiss art dealer and collector, who became "Europe’s pre-eminent dealer in modern art", according to "The New York Times", and "the greatest art dealer since the war", according to "The Daily Telegraph".  In 1982, he and his wife founded the Beyeler Foundation to show his private collection, which on his death was valued at US$1.85 billion. Jonathan Lopez is an American writer and art historian.  Born in 1969 in New York City, he was educated there and at Harvard.  He writes a monthly column for Art & Antiques called "Talking Pictures" and is a frequent contributor to London-based Apollo: The International Magazine of the Arts.  His noted December 2007 "Apollo" article "Gross False Pretences" related the details of an acrimonious 1908 dispute between the art dealer Leo Nardus and the wealthy industrialist Peter Arrell Brown Widener of Philadelphia.  Lopez has also written for ARTnews, the Associated Press, U.S. News & World Report, The Boston Globe, The International Herald Tribune, and the Dutch newsweekly De Groene Amsterdammer.  His book, "The Man Who Made Vermeers" is a biography of the Dutch art forger Han van Meegeren. Jacques Goudstikker (August 30, 1897 – May 16, 1940) was a Jewish Dutch art dealer who fled the Netherlands when it was invaded by Nazi Germany during World War II, leaving an extensive and significant art collection including over 30 "Old Masters" which was looted by the Nazis.  "Between the two World Wars, Jacques Goudstikker was probably the most important Dutch dealer of Old Master paintings", according to Peter C. Sutton, executive director and CEO of the Bruce Museum of Arts and Science.  The Dutch government restored the paintings to the Goudstikker family in 2006, and they were sold at auction in 2007 for almost $10 million. Johannes de Renialme (Antwerp, ca. 1600 – buried Amsterdam, 20 April 1657) was a Dutch art dealer, active in Amsterdam and Delft between 1640 and 1657, notable for the scale of his dealings.  De Renialme was known for being a dealer of Rembrandt, Hercules Seghers, Jan Lievens and Salomon Koninck.  Among his clients was Frederick William, Elector of Brandenburg.
