Samuel Willenberg, 92, the last known living survivor of the Treblinka death camp, tells his story of horror and triumph in new WLRN documentary premiering Tuesday in Miami.

The Nazis created mock transit stations, complete with nonworking painted clocks, and posted time table schedules to give the impression that their Jewish victims were solely there for transport to colonies where they would be safe.
