Events were held across the city Monday for Holocaust Remembrance Day.
In one gathering in Manhattan, survivors shared their personal stories with groups of students at the Museum of Jewish Heritage.
They also spoke about artifacts that they donated to the Lower Manhattan museum.
Organizers said it's important to discuss the Holocaust to ensure it never happens again.
"I took hundreds of interviews from survivors that are no longer here, but their stories, what happened during the war, will go on forever," said Ray Kaner, a Holocaust survivor.
"I'm trying to do that little bit that I can by telling my story to children and trying, young people, and hoping that they will tell others about this and hoping that maybe, that will make a little impact," said Inge Oppenheimer, a Holocaust survivor.
The Museum of Jewish Heritage was established in 1997 and honors Holocaust Remembrance Day every April.
