Erika Rosenberg was born in a family of German Jews in Buenos Aires, Argentina. Her parents, a lawyer and a doctor, fled in 1936 via Paraguay to Argentina and escaped the Holocaust.

In 1990 she met Emilie Schindler first time. Their intensive conversations are documented in more than 70 hours of recordings from which Rosenberg made the biography "In Schindlers Schatten" in 1997.

After Emilie Schindler's death on October 9, 2001, Erika Rosenberg was appointed one of her heirs, as their common work also led to a great friendship.

Since 2009 Erika Rosenberg represents Argentina at the International Council of the Austrian Service Abroad.
