Florida's Three Comma Club

In March, Forbes released its annual list of billionaires or, as the editors call it, The Three Comma Club.

Out of 2,208 members across the globe, 51 reside in Florida - and, of those 51, more than half are reportedly based in the South Florida area.

Many of them are immigrants - self-made men who made their money through hard work and perseverance. Others expanded upon existing family fortunes, impressively increasing their net worth through skilled leadership and smart investments.

The sources of their riches vary as well, from traditional avenues like banking and wealth management to more colorful routes like fast food and cruise ships. Many opt to reside in Palm Beach, with several taking on second careers in sports: Four are involved in the leadership of NFL, NBA or MLB teams.

Join us as we get to know the state's 10 wealthiest individuals, including a look at how they amassed such riches.

The richest man in Florida (not to mention the 57th richest person in the world, according to Bloomberg) was once a Hungarian refugee who arrived penniless in the United States at age 21. THOMAS PETERFFY was a quick learner who went from computer programmer to the founder, chairman and CEO of Interactive Brokers, one of the top brokerage firms in the country. Now 73, he resides in Palm Beach but says he has no plans to formally retire.
