Lacoste's crocodile was the first-ever designer logo

In the 1920s, René Lacoste was a superstar tennis player who won seven Grand Slam championship tournaments throughout his career. His fans nicknamed him "The Crocodile" and he emraced it by having a logo of a crocodile embroidered on his blazer and polos. It became his personal brand before anyone had such a thing. Once he retired in the 1930s, he started a company called "La Chemise Lacoste" that sold shirts with his crocodile logo on them.
