André Weil

André Weil, Simone Weil’s brother, was a mathematical prodigy whose childhood unfolded in a household that placed intellectual development above play. By nine he was solving advanced mathematical problems; by twelve he had taught himself classical Greek and Sanskrit and developed skill on the violin. He later joined the Institute for Advanced Studies at Princeton.

Childhood and Education

Their mother, Selma Weil, banned toys and dolls from the home, believing such trifles hindered intellectual development. She took charge of the children’s education and planned each element of their intellectual growth. The household’s discipline thus had a practical as well as an intellectual dimension: its children were steered away from conventional play and toward demanding study.

André’s precocity appeared early in mathematics and extended to languages and music. By twelve he had taught himself two classical languages, Greek and Sanskrit, alongside his violin playing. The account presents these pursuits as part of an unusually wide-ranging education, not solely as preparation for his later mathematical career.

Intellectual Life with Simone Weil

André and Simone grew up in a close intellectual environment. Although Simone is described as slower than her brother, she was reading the newspaper to the family by five and mastered Greek and several modern languages in her early teens. The siblings often communicated in Greek or in rhymed couplets, making language itself part of their shared play and exchange.

Their studies could also become collaborative: Simone told André that she had completed a Latin composition and was ready to study Aeschylus with him. The episode shows her addressing him as a fellow learner, while their exchanges in Greek and verse suggest a childhood in which scholarly accomplishment and sibling communication were closely intertwined.

Later Career and Significance

André later joined the Institute for Advanced Studies at Princeton, the clearest indication in the account of the direction his early mathematical promise took. The brief portrait sets his exceptional gifts beside Simone’s own intellectual development: the two children were shaped by the same demanding home, yet the account identifies André in particular through his mathematical prodigy and broad early accomplishments.
