Sam Walton

American entrepreneur who founded Walmart in 1962 — building it into the world's largest retailer — through relentless cost reduction, rural market focus, supply chain innovation, and a distinctive employee culture of autonomy with accountability.

Created the most efficient retail supply chain in history and proved that rural America was underserved — Walmart's distribution network, cross-docking, and supplier management created cost advantages that no competitor could match; the company's success also demonstrated that rural and small-town consumers had been systematically underserved by retailers focused on cities.
