Hi,

James H. Simons likes to play against type. He is a billionaire star of mathematics and private investment who often wins praise for his financial gifts to scientific research and programs to get children hooked on math.

(This comes from bostonglobe.com Unique setbacks, successes paved inspiring career path by William J. Broad New York Times on July 08, 2014.)

What does the bold part mean?

Thanks in advance!

    He's a billionaire.
    He's a star (he's famous, at least among those who know mathematicians and investors :D, and hugely successful)
    His original field was mathematics.
    He got rich through private investments.
