Answer:
One artist who paved the way for conceptual art with his ready-mades was Marcel Duchamp. Duchamp was a French artist who was active in the early 20th century, and he is best known for his pioneering work in the fields of Dada and Surrealism. Duchamp is often credited as being one of the founders of conceptual art, and his ready-mades - which were everyday objects that he selected and displayed as works of art - were a major influence on the development of this artistic movement. Duchamp's ready-mades challenged traditional notions of what could be considered art, and they paved the way for later conceptual artists who sought to question and explore the nature of art itself.
