(Forbes) In the increasingly crowded world of flashy activist hedge fund managers, Patrick Walsh, 39, plays against type. The founder of the $150 million PW Partners in Chicago wasn’t schooled at Wharton and has no Ivy League pedigree or M.B.A. He didn’t apprentice with hedge fund greats like Carl Icahn, Dan Loeb or Bill Ackman, and he eschews the public spats that make activists a favorite of the news media. He’s got no public relations handler or even an in-house trader to execute his stock moves.
