A wave of exhibitions and projects is celebrating the 90th anniversary of the births of Christo and Jeanne-Claude, the late husband-and-wife duo known for monumental environmental installations. Their nephew Vladimir Yavachev, who directs their foundation, is overseeing the realization of their final permanent work, *The Mastaba* in Abu Dhabi, while temporary works like *The Gates* in Central Park are being revived through augmented reality. The anniversary also marks 30 years since *Wrapped Reichstag* and 20 years since *The Gates*.
This moment matters because it underscores the enduring influence of Christo and Jeanne-Claude, who redefined public art through ephemeral, large-scale projects that could not be bought or possessed. Their commitment to temporary beauty challenges conventional notions of art ownership and permanence, and the use of technology to recreate their works highlights new ways to preserve and experience art that was designed to disappear.
