In 1936, she was appointed to the Brazilian Consulate in
Hamburg, Germany, where she was made the Chief of the Passport Section. She started to help Jewish people during
Kristallnacht, on 9 November 1938. She handed out
visas to
Jews without the red "J" that identified them as such, since Brazilian Dictator
Getúlio Vargas non-officially denied visas to Jews. She was in close relations with
underground activists in Germany and would even grant visas to Jews that she knew had forged passports. In 1938 she met fellow diplomat and assistant-Consul
João Guimarães Rosa, who would later become her second husband, and one of the most important Brazilian writers. His magnum opus,
Grande Sertão: Veredas, was dedicated to her. With his help, she intensified her humanitarian activity, saving a great number of Jews from imprisonment and death. She remained in Germany until 1942, when Brazil broke relations with Germany and joined the
Allied Forces. ==Recognition==
