To commemorate the 70th anniversary of the liberation of Auschwitz this week, the Fusion media network put together a moving video incorporating the work of famed writer Primo Levi and narration from a survivor of the camp.

In the clip, Roman Kent reads the words of writer Levi, who died in 1987 and was himself a Shoah survivor.

From Levi’s poem “Stranger:”

“For you and for your children, the ashes of Auschwitz are a warning…that the terrible fruit of hatred, whose traces you saw here, will never grow a new seed, neither tomorrow nor ever.”

From Fusion:

Next week marks the 70th anniversary of the liberation of Auschwitz, Nazi Germany’s largest concentration and extermination camp, where more than 1.1 million men, women and children were murdered between 1941 and 1945.

Fusion partnered with the USC Shoah Foundation to mark this historic anniversary and the commemorative events taking place around the world on January 27, the day when in 1945, the Soviet Army arrived at Auschwitz.

This video blends images from our recent visit to Auschwitz with the words and voices of two of the camp’s most remarkable survivors: the writer Primo Levi—best known for his account of his year at the camp, If This Is A Man—and Roman Kent, the president of the International Auschwitz Committee.
