David Seymour, known as Chim, didn’t shine in the spotlight like his more famous Magnum colleagues. But a retrospective opening this week shows him to have been a master chronicler of 20th century Europe.

We Went Back: Photographs from Europe 1933–1956 by Chim is on view at the ICP museum from January 18 to May 5, 2013.
