BEST DISPLAY OF WEALTH Leonard M. Miller family The current building and real-estate boom has been very good to Miami-based Lennar Corporation, the nation's premier home-construction company, which is now pulling in more than six billion dollars in annual revenues. This past December the family of company founder Leonard Miller, who died in 2002, donated a whopping $100 million to the University of Miami's medical school, now renamed the Leonard M. Miller School of Medicine. It's the biggest gift in UM's history, and it says "We're filthy rich" in a very classy way.
