I guess it shouldn't come as such a huge surprise given his name is emblazoned on prominent buildings across the Austin and Round Rock, but Michael Dell was named #18 on Forbes list of America's 50 Top Givers. Dell donated $100 million in (0.6 percent of his wealth), with a total lifetime giving of $914.4 million. Half of this year's donations went towards the Dell Medical School on UT Austin's campus, expected to start enrollment for the 2016 school year. Bill Gates topped off the list giving $1.9 billion in 2012 alone. Dell's total net worth is estimated on the order of $15.9 billion and he ranks #25 on Forbes' list of richest Americans.
