Estee Lauder

American entrepreneur who co-founded Estée Lauder Companies — starting by selling her uncle's skin cream formulas — and built one of the world's largest beauty companies through personal demonstration, department store placement, and the gift-with-purchase innovation.

Invented the gift-with-purchase marketing technique — offering a free product with every purchase — which drove trial, created loyalty, and forced department stores to give her coveted counter space; and demonstrated that personal selling (touching every customer's face, demonstrating product) builds brand trust that advertising cannot.
