Roman Kent, who as an orphaned teenager endured the horrors of Auschwitz and other hellish camps, and later channeled his sorrow and rage into helping to lead an American movement to memorialize the Holocaust and provide reparations for aging Jewish survivors, died May 21 at his home in Manhattan. He was 92.

While many Holocaust survivors have chosen to stay quiet about their experiences or share them only with close friends and other survivors, Mr. Kent believed that the world needed to be reminded of the six million Jews who perished at the hands of the Germans and their collaborators, and that Germany needed to repay the remnants of European Jewry for what they suffered and whom they lost. He and a handful of others did the painstaking work of galvanizing and organizing survivors into a movement.

Mr. Kent was chairman of the American Gathering of Jewish Holocaust Survivors and Their Descendants. In 1988, he joined the board of the Conference of Jewish Material Claims Against Germany, which has negotiated most of the $80 billion that Germany has paid in assistance to survivors and for educational and memorial programs. At various times, Mr. Kent was president of the International Auschwitz Committee, also the Jewish Foundation for the Righteous, which provides aid to non-Jews who hid Jews or helped them escape.

Mr. Kent was a vigorous supporter of Holocaust education. In a speech he gave in 2015, on the 71st anniversary of the Lodz ghetto’s liquidation, he explained why. It was the obligation of adults, he said, to get children to understand “what happens when hatred and prejudice are allowed to flourish.”
