For 25 years, Henry Golde has spoken out to all kinds of groups.
"The most important thing as far as I'm concerned is telling kids in schools," he said
Kids will be our future leaders, he said, and the ones who may be able to keep our world free of another holocaust.
Golde was 11 when nazis invaded his homeland of Poland.
He'd spend the next 5-years in 10-different concentration camps, surviving each day on a piece of bread and a watery bowl of soup. Nearly six-million people who shared Golde's beliefs were killed, including his family.
"Many times i curse god, but then of course, i survived and i figured, well, there must be a higher being."
But it's a question he poses to each of the kids...
Was golde's improbable survival a lucky break? A miracle?
"I tell them to put themselves in my position because i was their age when it happened"
"He was pretty lucky with a lot of the situations because if he had gone one way, he wouldn't have made it," said eighth-grader Kate Gutkowski.
Still it's hard for Golde to hide his disappointment in many people around the world.
Apparently, many people have yet to learn the lesson world war two should have taught us.
"The strife of power and greed and recognition is as strong as before."
"You can look anywhere and see how people separate themselves into groups and eventually it could turn into another holocaust," eighth-grader Courtney Schoenberger said.
Golde said he'll never go back to see where the concentration camps were, because of all the bad memories there.
He's 75 years old, and lives in Appleton, where he's turned his story into the book "Rag Dolls."
Many of the South Middle School kids have read it.
