An Italian immigrant, Dr. Vincenzo Sellaro, and five compatriots; pharmacist Ludovico Ferrari, attorney Antonio Marzullo, sculptor Giuseppe Carlino and barbers Pietro Viscardi and Robert Merlo, created the organization to unite men and women of Italian heritage under one banner in order to preserve and disseminate the large cultural heritage of Italy.
