Antoni Tàpies (Barcelona, December 13, 1923 – Barcelona, February 6, 2012) was a Spanish painter, sculptor, and art theorist, considered one of the most influential artists of the 20th century and the leading exponent of informalism worldwide. His artistic legacy can be discovered at the Fundació Antoni Tàpies in Barcelona, located on Carrer d'Aragó, which also houses an extensive library dedicated to the study and research of his work.

Largely self-taught, Tàpies developed a unique style that fused tradition and innovation within an abstract language rich in symbolism. He was a pioneer in incorporating recycled materials and everyday objects into his creations: woods, fabrics, old doors, textile fragments, or discarded items, to which he gave new artistic and expressive meaning.

His work spans a wide range of disciplines, from painting on canvas and burlap to sculpture in bronze, wood, and iron. His graphic production is also extensive and highly valued by collectors worldwide. A particularly significant period was his involvement in the Dau al Set movement (1944-1952), which he co-founded and which marked a turning point in avant-garde art in Spain.

Recognized both nationally and internationally, Antoni Tàpies exhibited in the world's most prestigious museums, becoming an essential figure for understanding the evolution of contemporary art. His ability to transform the everyday into poetic matter places him among the great masters of modern art.
