Gustave Caillebotte
(1848 - 1894)
 

Gustave Caillebotte was a French painter who was a member and patron of the Impressionists, although he painted in a more realistic manner than many others in the group. Caillebotte was known for his early interest in photography as an art form.

The painting depicts the artist's brother, René Caillebotte, wearing informal clothes and standing at a balcony. He is standing at a window from the family home in the Rue de Miromesnil in Paris, looking outwards into Boulevard Malesherbes (the large, oblique cross-street in the background). It is a comparatively early work in Caillebotte's oeuvre and reveals his interest in urban Realism.
