Richest Americans You've Never Heard Of

Subway Founder Fred DeLucaMicrosoft's (MSFT) Bill Gates, Berkshire Hathaway's (BRK.A) Warren Buffett and Apple's (AAPL) Steve Jobs are all household names in addition to being among the wealthiest people in the country. There are, however, other billionaires, whose companies or products are also among the best-known in the country, yet they live in relative obscurity, unknown to most -- including their best customers.

Take Subway, which serves 2,800 sandwiches and salads every 60 seconds in the U.S. How many of its customers have ever heard of its founder, Fred DeLuca, who was 17 when he opened the first store? Or Peter Buck, the family friend who loaned DeLuca the $1,000 that got the company off the ground back in 1965?

Likewise, Enterprise Rent-a-Car is the largest rental-car company in the U.S., but how many of its customers are familiar with Jack Crawford Taylor, the man who started the business back in 1957 and owns it to this day?

Every day, countless shoppers buy products made by Dole Food Company, the world's largest producer and marketer of fresh fruit, fresh vegetables and fresh-cut flowers as well as packaged and frozen foods. Most people probably assume that Dole is owned by a large conglomerate, but in reality, a relatively unknown entrepreneur named David Murdock is Dole's sole owner. All net worth estimates mentioned below are credited to Forbes' World's Billionaire List for 2010.
