Forbes released their 2012 list of the world's billionaires Wednesday, and 18 Illinois residents made the list.
The roundup includes self-made businessmen like the Reyes brothers, and Michael Krasny, founder of CDW. There are also several big names from Chicago family legacies like the Wrigleys.
Noticeably under-represented are women, with two Pritzker daughters and Oprah holding their place.
Groupon's Eric Lefkofsky has risen quickly to the top edge of the list, but property baron Sam Zell retained the top spot as Illinois' wealthiest resident.
