Holocaust survivor Leon "Henry" Schwarzbaum has died at the age of 101.

Schwarzbaum died in Potsdam on Monday night, the International Auschwitz Committee reported on its website on Monday.

"It is with great sadness, respect and gratitude that survivors of the Holocaust all over the world say goodbye to their friend, fellow sufferer and companion Leon Schwarzbaum, who in the last decades of his life has become one of the most important contemporary witnesses of the Shoah," the committee said.

According to the committee, Schwarzbaum was the only one in his family to survive the concentration camps in Auschwitz, Buchenwald and a satellite camp in Sachsenhausen.

According to the information, he later lived as an art and antiques dealer in Berlin.

Reports as witnesses

Schwarzbaum was to be questioned in the ongoing trial of a suspected former SS guard at Sachsenhausen concentration camp in Brandenburg/Havel.

However, according to the court, this was not possible due to his state of health.

In 2016 he testified before the Detmold district court in the trial against the former SS guard at Auschwitz concentration camp, Reinhold Hanning.

For decades, Schwarzbaum had reported on his experiences from 1939 to 1945, for example in schools or training companies.

For this he was awarded the Federal Cross of Merit in 2019.
