Leon Uris
Private First Class
American novelist who served as a Marine at Guadalcanal and Tarawa in World War II. His experiences inspired the bestselling novel "Battle Cry" (1953), and he later wrote "Exodus" about the founding of Israel and the masterful WWII epic "Mila 18" about the Warsaw Ghetto Uprising.

John Vianney
French Catholic priest who was conscripted into Napoleon's army but deserted, later pardoned under a general amnesty. He became the patron saint of parish priests and was canonized in 1925.

Raoul Wallenberg
Swedish diplomat who saved tens of thousands of Hungarian Jews during the Holocaust by issuing protective passports and sheltering them in buildings designated as Swedish territory.
