Isabelle Rimbaud

French writer, editor and biographer, and the youngest sister of famous poet Arthur Rimbaud and the wife of Pierre-Eugène Dufour (1855-1922), better known as Paterne Berrichon. She inherited Arthur Rimbaud's estate after his death in 1891 and became his literary executor.

Among the known letters of Arthur Rimbaud, several were exchanged with his sister Isabelle. When Arthur Rimbaud returned to Marseilles on 23 August 1891, Isabelle went with him. In her letters to her mother, she described the last weeks of Arthur Rimbaud's life. She wrote down her brother's last letter dictated by him on 9 November 1891 and added his last words before the midday sun the following day. She witnessed his great sufferings and was present during his death throes on the night of 9-10 November 1891. Isabelle was the last person to have sketched her dying brother.

She married Paterne Berrichon in 1897. They both strove to be the guardians of the poet's good name. She died on 20 June 1917, aged 57, of cancer in Neuilly-sur-Seine.
