On a Thursday evening in February, Ai Wei Wei, the Chinese artist-dissident, appeared on the big screen at the Auditorium at 66 West 12th Street to address government censorship during an event, “Fear of Art.”

At the same time, just up the street at the University Center, New School alumna and documentary filmmaker Laura Poitras, journalist Glenn Greenwald, and New York Times columnist David Carr gathered to speak, in front a sold out audience, with none other than Edward Snowden, who appeared live via a video link. The topic of the discussion was Poitras’ new film, CitizenFour.

It was just another day at The New School—and the start of another year of memorable moments that included visits from prominent figures such as Frank Gehry, Noam Chomsky, bell hooks, and Sarah Koenig and milestones such as the 40th anniversary of the School of Media Studies, the opening of the College of Performing Arts’ new spaces, the unveiling of Glenn Ligon’s installation For Comrades and Lovers at the University Center, and the launch of The New School’s new visual identity.

Take a look back at 20 of the most memorable moments of 2015 at The New School.
