The Ferragamos
After studying his shoe craft in Naples, Salvatore Ferragamo, then 13, set up his first shop in his hometown of Bonito, Italy in 1912. Two years later, he immigrated to the US, learned factory techniques, and by 1923 was dubbed “Shoemaker to the Stars” in Hollywood. At the time of his death in 1960, Salvatore’s widow, Wanda Ferragamo, took the helm with the help of the couple’s six children—Fiamma, Giovanna, Fulvia, Ferruccio, Leonardo and Massimo. Today, the siblings continue the family name with the help of their children.

Her own daughter, Miuccia, joined the business in 1977, and together with leathergoods manufacturer (and later husband) Patrizio Bertelli, moved the house in a completely new direction. Forgoing imported products in favor of a line of handbags, and later ready-to-wear, Miuccia’s creativity and Bertelli’s business acumen turned Prada into one of the world’s top-selling fashion lines.

The Versaces
Donatella Versace currently runs the house of Versace, taking over the business after her brother and founder Gianni Versace passed away tragically. Gianni built a booming business (which he founded in 1978) in the ’80s and ’90s and the company now flourishes under Donatella’s leadership.

Wang works alongside with his brother Dennis, who holds the title chief principal officer, and sister-in-law and CEO Aimie—parents to an oft-photographed, very fashionable little girl.

The Wertheimer Brothers, Chanel
You may associate Chanel with all things Karl Lagerfeld, but behind the scenes, Alain and Gérard Wertheimer are in charge of running one of the world’s most famous fashion houses. The brothers’ grandfather, Pierre, purchased 70% of the “Parfums Chanel” business (and its profitable Chanel No. 5 fragrance) in 1924. The duo also owns Eres lingerie, Tanner Krolle leather goods, and a number of French vineyards.
