Édouard Manet
(1832 - 1883)
 

In the Conservatory (French: Dans la serre) is an 1879 oil painting by Édouard Manet in the Alte Nationalgalerie, Berlin, depicting Manet's friends, a couple, in a conservatory. There is an ambiguity in the painting that has led art critics to characterize the couple's relationship in divergent ways. 

The setting is a conservatory at 70 Rue d'Amsterdam in Paris, then owned by painter Georg von Rosen and which Manet used as a studio for nine months in 1878 and 1879. Such a conservatory may have been more than a greenhouse; French painter Alix-Louise Enault's Consolation depicted the Parisian conservatory as a "luxuriously decorated and intimate locale—a secluded indoor area conducive to private rendezvous".At first glance, we see a double portrait of a fashionable and attractive couple of some social rank. They are Manet's friends, the Guillemets, who owned a clothing shop. Their married status is conveyed by their rings, and the proximity of their hands is the nearest hint of intimacy. The woman becomes the focus of the portrait, however, being more prominently placed and colourfully dressed. Their physical separation—with the husband Jules slouching in dark clothing behind the bench—their lack of engagement with the viewer, and their abstract gazes create a sense of detachment, which has been the primary theme in modern criticism of the work.

Claude Monet 
(1840 - 1926)
 

Woman with a Parasol – Madame Monet and Her Son, sometimes known as The Stroll (French: La Promenade) is an oil-on-canvas painting by Claude Monet from 1875. The Impressionist work depicts his wife Camille Monet and their son Jean Monet in the period from 1871 to 1877 while they were living in Argenteuil, capturing a moment on a stroll on a windy summer's day.

 Édouard Manet
(1832 - 1883)
 

Nana is a painting by French painter Édouard Manet. It was completed in 1877 and was refused at the Salon of Paris the same year. Manet decided to show his painting in the window of a shop on the Boulevard des Capucines, one of Paris’s main streets. The painting gathered attention and crowds during its exhibition, due to Manet's fame in Paris. The work is now at the Kunsthalle Hamburg art museum in Germany. 
The painting shows a young and beautiful woman who stands before a mirror with two extinguished candles, her face turned to the spectator. Her dress is incomplete; she wears a white chemise, blue corset, silk stockings and high-heeled footwear. The interior suggests that it is a boudoir. Behind the woman is a sofa with two pillows. An elegantly dressed man, sitting on the sofa, can be partly seen on the right of the painting. On the left side, there is a chair, a table and a flowerpot. 
Both the title and the numerous details suggest that the picture represents a high class prostitute and her client. "Nana" was a popular assumed name for female prostitutes during the second half of the 19th century (much like the connotation "Candy" has had for English-speakers more recently). Even today the French word "nana" is used to describe a frivolous woman (or simply "a female" in argot).
The model for the painting was Henriette Hauser, a well-known courtesan of the era.

Claude Monet 
(1840 - 1926)

Though Monet preferred painting in the open air, for this work he brought his easel indoors to capture his first wife, Camille Doncieux, sitting at her embroidery loom. Quietly absorbed in her task, Monet's figure recalls the scenes of 17th-century Dutch masters, who were enjoying a revival in France at the time. Even indoors, light remains a primary concern for the artist; the touches of white flicker across the front of Camille's dress, creating a tapestry-like texture that perhaps alludes to her work on the loom.

Édouard Manet
(1832 - 1883)
 

Chez Tortoni is a painting by the French artist Édouard Manet, painted ca. 1875.  

The painting depicts an unidentified gentleman sitting at a table in the Café Tortoni de Paris while drawing on a sketchpad. A half-empty glass of beer stands on the table.

Chez Tortoni hung in the Isabella Stewart Gardner Museum of Boston, Massachusetts, United States prior to its theft in 1990 and it has not yet been recovered. 
A $10 million reward is offered for the return of Chez Tortoni and the other stolen items.

Claude Monet 
(1840 - 1926)
 

With the outbreak of the Franco-Prussian War, Monet and his newly wedded wife Camille fled to England for fear of Monet's military conscription. Returning to France in late 1871, the couple settled in Argenteuil along the Seine.  While many of Monet's paintings of trains come from the Gare St. Lazare Station, The Train in the Snow represents Argenteuil station, which was the artist's "commuter stop." At the time of Monet's residence, Argenteuil was located in a suburban section of France, connected by railway to Paris, Le Havre, and Rouen; trains and engines were in constant view at Argenteuil station because of their storage or redirection there.

Throughout the winter of 1874-1875, Monet continuously painted snow scenes in and around his home at Argenteuil. Fascinated by the trains traveling through his local station on their way to Paris, the artist worked on his paintings while standing on the station platform. Out of his many paintings of trains, Monet seems to have only painted three scenes from 1875-1876 that take place in the snow, including this particular painting.

 Édouard Manet
(1832 - 1883)
 

Argenteuil is an 1874 oil on canvas painting by Édouard Manet, first exhibited at the Paris Salon of 1875. It is one of Manet's first works to be regarded as a fully Impressionist painting due to its naturalistic style and its bold palette. The painting depicts a sailor and his companion sitting on a mooring dock surrounded by sailboats, the deep blue water of the Seine, and the town of Argenteuil on the far bank.
Manet's brother-in-law Rodolph Leenhoff posed for the figure of the man, who has an expression of intimacy in the painting; the woman, whose identity is unknown, appears less expressive, which the art historian Françoise Cachin attributes to the difficulty of posing for Manet

Art historians have described Argenteuil as a response to Claude Monet's depiction of similar subject matter.

Manet held the painting until his death. After his death, Henri Van Cutsem purchased it from Manet's widow, Suzzane Manet. Van Cutsem eventually bequeathed his collection to the city of Tournai, Belgium where the painting currently resides in the Musée des beaux-arts.
