The family name associated with the Italian luxury fashion company founded by Mario Prada in 1913 is Prada.
Mario Prada and his brother Martino opened a luxury leather-goods shop in Milan in 1913. The business initially sold travel goods, handbags, and accessories rather than the ready-to-wear collections for which Prada is now especially famous.
Mario’s granddaughter Miuccia Prada joined the family business in 1978 and transformed its direction. She introduced influential nylon bags and developed Prada into a major international fashion house. Her husband, Patrizio Bertelli, became an important business partner and executive, helping industrialize and expand the company.
The brand Miu Miu was created by Miuccia Prada in 1993 and is part of the Prada Group. It is a sister brand, not a separate family unrelated to Prada. The company’s history therefore combines a 1913 family shop with later design and corporate expansion.
