What was the name of Salvador Dalí's younger sister?

Salvador Dalí’s younger sister was named Anna Maria. She was born in 1908, three years after Dalí, and grew up with him in Figueres and Cadaqués in Catalonia.

Anna Maria became an important early model and observer of her brother’s artistic development. Dalí portrayed her repeatedly, especially during the 1920s, when he was experimenting with different styles before becoming internationally famous as a Surrealist. One well-known example is Girl at a Window, painted in 1925, which shows Anna Maria looking out toward the landscape at Cadaqués.

Their relationship later deteriorated. Anna Maria’s political sympathies and her criticism of some aspects of Dalí’s life and relationship with Gala contributed to a lasting estrangement. During the Spanish Civil War, she was imprisoned and reportedly tortured by Republican forces, an experience that affected Dalí’s views of the conflict.

Readers may encounter her name as Ana Maria or Ana María, reflecting Spanish usage and translation conventions. Those forms refer to the same person; “Anna Maria” is the conventional English-language answer used here.
