About the article "Bedroom in Arles", section "First version".

Candidate passages:
Eugène Boch (1855–1941) was a Belgian painter, born in Saint-Vaast, Hainaut, who was the younger brother of Anna Boch, a founding member of Les XX.
Born into a wealthy dynasty of manufacturers of fine china and ceramics, still active today under the firm of Villeroy & Boch, Eugène Boch enrolled in the private atelier of Léon Bonnat in Paris, in 1879.
Since 1882, when Bonnat closed his atelier, he studied at the atelier of Fernand Cormon.
Paintings of him were admitted to the Salon in 1882, 1883 and 1885.
In June 1888, he was introduced by Dodge MacKnight to Vincent van Gogh.
The portrait was executed in the first days of September 1888, a few days before Boch's departure.
In the first version of Van Gogh's Bedroom, executed in October 1888, this portrait is shown hanging to the left of the portrait of Paul-Eugène Milliet.
Arranged this way, both portraits may have formed part of the Décoration for the Yellow House.
When Eugène Boch died in 1941, he bequested "The Poet" (that is Van Gogh's title for his portrait of Eugène Boch, which Boch received from Johanna van Gogh-Bonger as a present in July 1891) to the Louvre. 
Eugène Boch (1 September 1855 – 3 January 1941) was a Belgian painter, born in Saint-Waast, Nord, Hainaut, and the younger brother of Anna Boch, a founding member of Les XX.
Born into the 5th generation of the Boch family, a wealthy dynasty of manufacturers of fine china and ceramics, still active today under the firm of Villeroy & Boch, Eugène Boch enrolled in the private atelier of Léon Bonnat in Paris, in 1879.
From 1882, when Bonnat closed his atelier, he studied at the atelier of Fernand Cormon.
Paintings of his were admitted to the Salon in 1882, 1883 and 1885.
In 1888, he was introduced by Dodge MacKnight to Vincent van Gogh.
In 1892 he settled in Monthyon (Seine-and-Marne), not far from Paris.
In 1909, he married Anne-Marie Léonie Crusfond (?-1933), in 1910 they moved to their recently erected chalet "La Grimpette", where both lived until their death.
Like his sister Anna Boch, Eugène supported artists of talent, but without money, including Émile Bernard, whom he met at the Atelier Cormon, and Paul Gauguin.
Or he exchanged works, as with van Gogh.
Thus little by little, an important collection of contemporary art came together.
Besides his own portrait Eugène Boch owned a second van Gogh painting.
Like his sister Anna, Eugène Boch spent a large part of the funds, which they owed to their father's,Victor Boch, business success, on promoting other artists.
They bought pictures from virtually all leading contemporaries of their time, the majority of whom were also their friends.
Upon Eugène Boch's death in 1941, he bequeathed "The Poet" – that is Van Gogh's title for his portrait of Eugène Boch, which Boch received from Johanna van Gogh-Bonger in accordance to the last will of Vincent and Theo – to the Louvre.
Today the painting can be seen in the Paris Musee d'Orsay.
Part of his collection was bought by his great nephew Luitwin von Boch with the idea to make a Museum on Anna and Eugene Boch. 
Besides her own paintings, Boch held one of the most important collections of impressionist paintings of its time.
She promoted many young artists including Vincent van Gogh whom she admired for his talent and who was a friend of her brother Eugène Boch.
"The Vigne Rouge" ("The Red Vineyard"), purchased by Anna Boch, was long believed to be the only painting Van Gogh sold during his lifetime.
The Anna Boch collection was sold after her death.
In her will, she donated the money to pay for the retirement of poor artist friends. 
Monthyon is a commune in the Seine-et-Marne department in the Île-de-France region in north-central France.
Residence of Eugène Boch, friend of Vincent van Gogh paint dans le portrait "le peintre aux etoiles".
Eugène Boch lived in the Villa La Grimpette. 
"The Red Vineyard" was exhibited for the first time at the annual exhibition of Les XX, 1890 in Brussels, and sold for 400 Francs (equal to about $1,000-1,050 today) to Anna Boch, an impressionist painter, member of Les XX and art collector from Belgium; Anna was the sister of Eugène Boch, another impressionist painter and a friend of Van Gogh, too, who had painted Boch's portrait ("Le Peintre aux Étoiles") in Arles, in autumn 1888.
Like "The Night Café", it was acquired by the famous Russian collector Sergei Shchukin, was then nationalised by the Bolsheviks with the rest of his collection, which eventually passed to the Pushkin Museum of Fine Arts in Moscow.
