Luis Martins de Souza Dantas (17 February 1876 – 14 April 1954) was a Brazilian diplomat who was awarded the title Righteous Among the Nations by Yad Vashem in June 2003, for his actions during World War II in helping Jews in France escape The Holocaust.

[citation needed] Luiz Martins de Souza Dantas was serving as the Brazilian ambassador to France and to the Vichy Government during the German occupation.

In a 1942 letter to Brazil's foreign minister Osvaldo Aranha, he said the camps set up by the Nazis were like something out of Dante's Inferno, where Jews were either slaves or were exterminated.

Chana Strozemberg, a woman from Poland, obtained a visa issued in January 1941, a month after the prohibition, but with false information.

[3] Eventually the investigation and suspicions of Luiz Martins de Souza Dantas were enough for him to be recalled by Getúlio Vargas, the Brazilian President of the time, where he faced disciplinary hearing for his actions.
