Ike Sewell was an American businessman and restaurateur, best known for co-founding the famous Chicago-style deep-dish pizza. He opened the first Pizzeria Uno in Chicago in 1943, which introduced this unique style of pizza to the public. Sewell's vision combined a thick, buttery crust with layers of cheese, toppings, and a chunky tomato sauce, creating a dish that became a staple in Chicago cuisine. Sewell's influence extended beyond just pizza; he played a significant role in the growth of the Chicago restaurant scene. His success with Pizzeria Uno led to the establishment of additional locations and inspired many other pizzerias to adopt the deep-dish style, solidifying his legacy in American culinary history.
