Sam Walton (1918 – 1992), the founder of Wal-Mart, grew up poor in a farm community in rural Missouri during the Great Depression. The poverty he experienced while growing up taught him the value of money and to persevere.

After attending the University of Missouri, he immediately worked for J.C. Penny where he got his first taste of retailing. He served in World War II, after which he became a successful franchiser of Ben Franklin five-and-dime stores. In 1962, he had the idea of opening bigger stores, sticking to rural areas, keeping costs low and discounting heavily. The management disagreed with his vision. Undaunted, Walton pursued his vision, founded Wal-Mart and started a retailing success story. When Walton died in 1992, the family's net worth approached $25 billion. Today, Wal-Mart is the world's #1 retailer, with more than 4,000 stores, including discount stores, combination discount and grocery stores, and membership-only warehouse stores.
