Born in Buenos Aires, Argentina, Marta Minujín studied at the Escuela Nacional de Bellas Artes. She gained international attention in the 1960s for her experimental performance art and immersive environments, becoming a central figure in the Latin American avant-garde movement.

Her practice is defined by the use of unconventional materials, including mattresses, cardboard, and food, to create monumental structures that are often designed to be destroyed or consumed by the public. Her work frequently critiques consumer culture and the ephemeral nature of art.

Minujín continues to be recognized globally for her contributions to conceptual art, with her works featured in major international exhibitions and institutional collections worldwide. Her practice remains focused on the intersection of public space, collective memory, and interactive experience.
