(CNN)Eighty years ago this month, Paris and northern France were occupied by German forces. Thousands of Jews and other refugees fled south from the Nazi onslaught. Many of them reached Bordeaux, finding temporary refuge while seeking life-saving visas through Portugal, a neutral nation, and on to the United States and other countries.

Some were lucky enough to reach the Portuguese consulate in Bordeaux, where the consul general, Aristides de Sousa Mendes, was granting life-saving transit visas to Portugal, contravening his government's orders.
    Earlier this month, the Portuguese parliament unanimously voted to honor Sousa Mendes, who was dismissed from his post and punished for his activities, by creating a monument for him at the National Pantheon.
