Born in Paris, France in 1905, Alfred Chagniot attended the Ecole des Beaux Arts. He was a follower of the post-impressionistic school, and a student of Montezin and Vuillaume.

A teacher by profession, he was known for his landscapes and seascapes of France, and took painting excursions to Greece, Italy, and Spain. His work shows the light color palette and broken brush technique of Impressionism.

Chagniot's paintings were shown at the Salon des Independants, Salon d'Hiver, at the Art Libre, the Ecole Francais, in Asnieres, Mantes, and Colombes, among others.

Among the numerous honors and medals the artist has received, the most important are: the Medal "Arts-Sciences-Lettres," the Merite Artistique, the Silver Medal of the Municipality of Paris, a distinction of the Society "Paysagistes Francais," the Fernand Renaud Prize, and major prizes of Asnieres,  Mantes, and other cities.

He was an Honourable Member of the jury and committees of the Salon "Artistes Francais" and the Salon "Paysagistes Francais."

Chagniot's paintings are in many public and private collections in the United States, Japan, Great Britain, the Municipality of Paris, and the French Government.

In 1982 he had a one-man exhibit in Paris, at Rue de Miro-mesnil.

The artist died in November, 1991.
