Bloch was the eldest daughter of Simon Bloch (1810–1879), founder and editor of the journal L'univers israélite.[2] She received a teaching license at the age of sixteen, and devoted herself to Jewish education. For two years, when she was about twenty-five years of age, she directed the institution for young girls at Lyon, founded by the local Jewish community.[3] Afterwards she co-directed the establishment of her sister Pauline Pereira in Paris.[4]
From June 1854 to August 1861, Bloch published a series of articles in her father's paper under the title "Lettres d'une Parisienne."[5] These articles provided complex analyses of French society, the role of women in Judaism, and the dangers of Jewish assimilation.[1] In a series of letters to Eugène de Mirecourt, she criticized the writer's negative descriptions of well-known Jews.[6]
She died of tuberculosis on 12 November 1868, at the age of 35.[1][7]
