Magic Johnson, Los Angeles Lakers

Johnson has invested so frequently and so much in ventures ranging from Aids-research organizations to Loews movie theaters and in franchises like Burger King, Starbucks, and 24-Hour Fitness clubs that it's hard to keep track. In 2011, Johnson joined Detroit Venture Partners, as a partner. The firm has invested in about 20 companies in the beleaguered city , which has bled hundreds of thousands of jobs, and most recently filed for bankruptcy protection.
