This photo was taken at the Rome tomb of Eugenio Zolli, former Chief Rabbi of Rome. After WWII in the 1940s he converted to Catholicism and took as his baptizmal name Eugenio in honor of the baptizmal name of the reigning Pontiff, a wartime hero.
He hid in the Vatican during the war, courtesy of Pius XII who welcomed him (saved him!).
Buy his book Before the Dawn and read it to your kids!
