The POPPER family crossed into Portugal. Jiri, Ella and Lisbeth POPPER traveled from Lisbon to Vera Cruz, Mexico on the vessel Quanza in August 1940. The family settled in Mexico.

Ernestine POPPEROVA and her son Jan POPPER traveled to Cuba. From there they sailed to New York on the vessel Mexico in November 1940.

Jiri POPPER was a prominent Czech banker. When he and his family left Prague in 1938, their home was appropriated by the Nazis and used as their Prague headquarters. At the end of the war, the Czech government claimed the home as national property and presented it as a gift to Russia in appreciation for that country’s role in liberating Prague. The Russians converted the home into an Embassy, which it continues to be to this day. The POPPER family has been fighting the Czech and Russian governments for the return of their home since 1945, but without success.
