Yechiel Granatstein (Hebrew: יחיאל גראנאטשטיין; June 6, 1913 – February 7, 2008) was a Polish-born Jewish author and writer in Yiddish and Hebrew, as well as a partisan fighter in World War II and a Jewish refugee activist following the Holocaust.
Even before World War II, he had developed his skills as a writer, writing for Dos Yiddish Tagblat and various Agudah periodicals.
Following the Nazi–Soviet invasion of Poland at the outbreak of World War II he escaped from the Germans to Slonim, which was on the Russian side of the Molotov–Ribbentrop line, eventually entrapped in the Słonim Ghetto after Operation Barbarossa.
He was accepted into the partisan unit because of his earlier training as a soldier and because he possessed an automatic machine gun.
It was in Paris in 1950 that he published an autobiography of his time fighting as a Jewish partisan under the title "I Wanted to Live" ("Ich hob gevolt lebn" in Yiddish), which detailed the dangers he faced not just from the German Nazis, but from his fellow Russian partisans as well.
