A Holocaust survivor spoke in Tulsa on Wednesday, sharing her story of survival. 

"At the end of World War II, our message was never again, but unfortunately, there are terrible situations; people are killed all over the world," said Eva Unterman. 

Eva says she was seven years old when Nazi Germany invaded and occupied Poland.

"First thing I remember was that I was not allowed to go to school, which I was really looking forward to, and then things became worse all the time," she said.

She says her family was taken to Auschwitz and then moved to a concentration camp called Stutthof. 

She was separated from her dad but was able to stay with her mom and grandma. 

"My grandma and a couple of other women went to hope to mend the socks, to give me the bread; I'm convinced of that. We never saw them again; they were killed," she said.

She says she thought the world had forgotten about them, but during the Battle of Dresden, she realized people were fighting against the Nazis. 

Eva has now spent years speaking to people about the Holocaust.

"People have not, for an unexplainable reason, learned to get along with each other because we have much more in common than we have that separates us; we're all human, first of all," she said.

She says at 91, she's trying to make a change by continuing to tell her story. 

"We have to stop hating each other, we must, if the human species is to survive," she said.

This is part of a free lunch and learn program at the Jewish Federation of Tulsa. 

They say they asked Eva to speak ahead of International Holocaust Remembrance Day on Saturday.
