Karl Lagerfeld

His 36-year tenure as creative director (1983–2019) and 54-year partnership with Fendi are the longest in fashion history, and he was the first to successfully revive a 'dead' house, setting the template for luxury turnarounds. Lagerfeld designed 8 collections per year, and introduced the iconic Chanel tweed suit in 300 new colorways. This data-led reinvention made Chanel’s logo the most recognized in fashion.
