Aristides de Sousa Mendes may not be a familiar name, but several people, along with their descendants, who owe their lives to him, are working to change that.

Aristides de Sousa Mendes was a Portuguese diplomat stationed in Bordeaux in the late 1930s who issued tens of thousands of visas to Jewish families, in direct violation of anti-Jewish laws instituted by Portugal’s fascist government at the time. For this act of resistance, Sousa Mendes faced trials and conviction, leaving him to live out the rest of his life in poverty and disgrace, and his 15 children scattered all over Europe and the U.S.
