UCI will mark the 20th anniversary of the fall of the Berlin Wall with a traveling photography exhibit and a four-day conference. “Icons of a Border Installation,” running through Nov. 2 in the Student Center, features images of wall remnants in unified Berlin. A conference called “1989: 20 Years After” is set for Nov. 5-8 and will feature a keynote address by Leszek Balcerowicz, Poland’s first post-communism finance minister. The photo exhibit is hosted by the German department and sponsored by the Goethe Institute of San Francisco. UCI’s Center for the Study of Democracy is hosting the conference.
