The smoke was still rising as Rabbi Herschel Schacter rode through the gates of Buchenwald.

It was April 11, 1945, and Gen. George S. Patton’s Third Army had liberated the concentration camp scarcely an hour before. Rabbi Schacter, who was attached to the Third Army’s VIII Corps, was the first Jewish chaplain to enter in its wake.

That morning, after learning that Patton’s forward tanks had arrived at the camp, Rabbi Schacter, who died in the Riverdale section of the Bronx on Thursday at 95 after a career as one of the most prominent Modern Orthodox rabbis in the United States, commandeered a jeep and driver. He left headquarters and sped toward Buchenwald.

By late afternoon, when the rabbi drove through the gates, Allied tanks had breached the camp. He remembered, he later said, the sting of smoke in his eyes, the smell of burning flesh and the hundreds of bodies strewn everywhere.

He would remain at Buchenwald for months, tending to survivors, leading religious services in a former Nazi recreation hall and eventually helping to resettle thousands of Jews.
