The Money: Spinal surgeon, prolific inventor and now venture philanthropist won a $1.3 billion settlement from Medtronic Inc. in 2005, ending four-year patent dispute. Also receiving an additional $50 million in $10 million increments. Michelson credits his accountant with a broad investment strategy that enables net worth to grow even as he shifts money to foundations.


Buzz: Michelson consults for Medtronic, but devotes most of his time to overseeing two foundations and a charitable trust that have combined endowments of more than $100 million. Gary Karlin Michelson Charitable Foundation focuses on supporting early cutting-edge research that's below the radar of government grant-makers. A companion medical research trust similarly provides two-year grants as bridge funding to promising graduate medical researchers. The dog owner also formed the Found Animals Foundation, which works toward more humane animal control services.
