João Crisóstomo is a humanitarian activist who has been a prime-mover in a variety of causes: the saving of the Stone Age engravings of Foz-Coa in Portugal (now designated a World Heritage Site); the struggle for the Independence of East Timor; and the recognition of three Holocaust rescuers: Aristides de Sousa Mendes, Luis Martins de Sousa Dantas, and Père Benoit. In 2000, following his involvement and contribution to the “Visas for Life” exhibit at the United Nations organized by Eric Saul and Rabbi David Baron, he was invited to join the International Raoul Wallenberg Foundation. João Crisóstomo has worked tirelessly for over 15 years to raise awareness and bring recognition to Aristides de Sousa Mendes.
