Who is credited with the development of the "ready-made" concept in art?

The development of the "ready-made" concept in art is credited to Marcel Duchamp. This innovative idea involved taking ordinary, manufactured objects and presenting them as art by merely selecting and designating them within an artistic context. Duchamp's famous piece, "Fountain," a porcelain urinal signed with a pseudonym, exemplifies this idea by challenging traditional notions of art and the role of the artist. By elevating everyday items to the status of art, Duchamp questioned what constitutes art and the art-making process itself, making him a pivotal figure in the Dada movement and later influencing conceptual art and contemporary practices.
