A Greek school will hand out diplomas to Holocaust-era students forced to flee during World War II.

Some 157 Jewish students escaped the city of Thessaloniki or were deported to camps by the Nazis, never finishing their education at the Italian School in the city.

Antonio Crescenzi, a teacher at the school, recently uncovered a collection of documents that has allowed him to track down those students or their descendants to help right the wrong.

Later this year, the school is set to host a ceremony, officially granting diplomas to the persecuted students, now either elderly or deceased.

Thessaloniki, Greece’s second largest city, also recently announced plans to open its first Holocaust museum. The city already has a memorial statue and a Jewish museum.

Prior to the war, Thessaloniki had an estimated 50,000-strong Jewish population. Today, only about 1,000 Jews live in the area.
