Simone Weil (/veɪ/; French: [simɔn vɛj]; 3 February 1909 – 24 August 1943) was a French philosopher, Christian mystic, and political activist.

After her graduation from formal education, Weil became a teacher. She taught intermittently throughout the 1930s, taking several breaks due to poor health and to devote herself to political activism, work that would see her assisting in the trade union movement, taking the side of the Anarchists known as the Durruti Column in the Spanish Civil War, and spending more than a year working as a labourer, mostly in auto factories, so she could better understand the working class.
