Joseph Greenblatt believes it was the antisemitic taunts he endured throughout his childhood in Warsaw that led him to a life of resistance. He was a key player in the 1943 Warsaw Ghetto Uprising, and then took on the Germans again, this time with the Polish Home Army in the Warsaw Uprising of 1944 — for which he later received a medal.

Greenblatt’s testimony, recorded in New York City in 1996, is contained in USC Shoah Foundation’s Visual History Archive.

"During the Holocaust I was living in a cocoon, with blinders. I lived completely in the present moment, because at any second, any Nazi, any German, any Kapo, could do away with me. You were like a gnat that they could squash. So, you lived inside a cocoon and hoped that one the day the butterfly would come out."
