Modern pizza has been attributed to baker Raffaele Esposito of Naples. In 1889, Esposito who owned a restaurant called the Pizzeria di Pietro baked what he called "pizza" especially for the visit of Italian King Umberto I and Queen Margherita.
Pizza as we know it today came from Focaccia Bread ( Flat Bread ) that has been prepared for hundreds if not thousands of years in Italy. The Focaccia Bread was made with herbs, honey, tomatoes, olives, and nuts. In Italian the word Pizza means any.
The pre-modern origins of pizza during the antiquity, Middle Ages, and Renaissance are shrouded in mystery. This is possibly a Renaissance baker, baking her products in a pan held over open fire. The ancient pizzas were possibly baked in this manner. (The origin of this image is unknown.)
