Christo and Jeanne-Claude were a husband and wife born on the same date who created expansive works of art situated in the environment. They are most well known for their "Wrapped" projects, in which large monuments, buildings, and public spaces were wrapped in materials such as nylon, polyester, and polyamide fabrics with rope. The Pont-Neuf bridge in Paris, the Museum of Contemporary Art in Chicago, a Roman wall in Rome, and the Gates in Central Park in New York City have all be wrapped by Christo and Jeanne-Claude. Christo states, "I am an artist, and I have to have courage ... Do you know that I don't have any artworks that exist? They all go away when they're finished. Only the preparatory drawings, and collages are left, giving my works an almost legendary character. I think it takes much greater courage to create things to be gone than to create things that will remain."
