Blanche Hoschedé was born in Paris, the daughter of Ernest Hoschedé, a businessman and department store magnate. Ernest was an art collector and important supporter to Monet early in his career. In 1877 Ernest went bankrupt and he, his wife Alice, and their six children moved in with the Monet family. Ernest spent most of his time in Paris and then Belgium, and after Monet’s wife Camille died in 1879, Monet began a relationship with Alice.
In the meantime, Blanche had developed an interest in painting, and by the time she was 17 she was Monet’s student and assistant, often painting alongside him in the open air.
In 1897, Blanche married Jean Monet, and moved to Rouen where she remained until Claude’s death in 1914. She then moved back to Monet’s house in Giverny and took care of him, the household, and the famous gardens.
Most of Blanche’s paintings were made in Giverny between 1883-1897, and are very similar in subject matter and technique to Monet’s. Her subsequent paintings show a greater individuality, and are often landscapes created beside the Risle river.
After Monet’s death, Blanche was able to concentrate more on her artistic career, and exhibited her work in Paris at Galerie Bernheim-Jeune, Galerie Daber, and Galerie d’Art Drout Provence. Her work was also often shown in the Salon des Indépendants, from where the legendary art dealer of the Impressionists Paul Durand-Ruel bought one of her paintings in 1905.
