Zigi Shipper, 88, who was born in Poland, was taken to a concentration camp at the age of 14 because of his Jewish background.
He has spoken to Express.co.uk about his time at Auschwitz and Stutthof concentrations camps, and the horrors he witnessed there.
Zigi has an important message on Holocaust Memorial Day, which falls today, Saturday 27 January.
“We must never forget what happened,” said Zigi, who speaks regularly to audiences about his experience.
“We need to love each other as human beings. It doesn’t make any difference what religion you are.
He continued: “I don’t care about your religion – as long as you’re a good person.”
Asked if he thinks enough has changed since the Holocaust, he said: “I don’t think we have learned.
“We still see people fighting with guns – but we need to love each other, not hate each other.”
Asked if he still believes in God after living through the Holocaust, Zigi said simply: “I don’t know – but I’ll never deny it.”
He added: “If there is a god there isn’t one for the Jews and Christians and Muslims – it’s the same one.”
Zigi believes it is important for him to speak to audiences as long as he can – because “there are not many Holocaust survivors left”.
“I’m one of the young ones and I was 88 last week.”
When was the Holocaust?
The Holocaust was a mass genocide which occurred between January 1933 to May 1945.
During this time, six million Jews – over two thirds of the Jewish population – were murdered by the Nazis.
A further five million more people were killed who were not of the Jewish faith, including Polish people, Soviet prisoners of war, disabled and the Romani people.
