Holocaust Victims’ Auschwitz Items Rediscovered After 50 Years

16,000 Belongings of Auschwitz Victims Rediscovered 0:40

MAINZ, Germany — The personal belongings of thousands of Holocaust victims have been found after more than half a century, officials said Tuesday.

More than 16,000 objects — including fragments of shoes, jewelry, watches, and keys — were excavated in 1967 near a gas chamber and crematorium at Auschwitz.

They were likely the last personal belongings of Jews and other victims being led to their deaths by the Nazis.

However, the Auschwitz-Birkenau State Museum registered only around 400 of these items in its collection and only recently realized there could be more after watching a documentary about the dig.

Officials began a painstaking search over "several months of investigation," according to museum director Piotr M. A. Cywiński.

"Individually verified trails were broken, people working then in the museum were no longer there," he said in a statement. "Unfortunately the author of the film has already died, the institutions which created the movie have changed, and the archives were silent. Nevertheless, we checked every lead."

Eventually they were able to make contact with the last person alive who took part in the excavation and found that the missing pieces were stored in 48 cardboard boxes at the Polish Academy of Sciences.

While Cywiński said that he "can only try to imagine why the lost objects were deposited in these boxes," he speculated the climate of anti-Semitism in Polish politics at the time might have contributed.

The items were transported to the museum last week.

More than 1.1 million people, including 900,000 Jews, were murdered by the Nazis at Auschwitz between 1940 and January 1945.
