Walmart is America’s largest brick-and-mortar retailer, and its success has largely been guided by the influence of its founder, Sam Walton.

After he butted heads with the chain’s management, he decided to open his own stores. The first Wal-Mart opened in 1962, and by 1976 the company was worth more than $176 million.
