Most entrepreneurs take a while to find their focus. Philip E. Rollhaus Jr. has taken the better part of three decades. He is founder and chief executive of Chicago-based Quixote Corp., which sells highway crash guards and cushions. Under his leadership, the company has lived up to the idealism—and folly—of its namesake. In his time, the stocky, bright-eyed, 64-year-old Rollhaus has dabbled in court-reporting technology, compact-disc manufacturing (dmi), a still-unproven method for manufacturing artificial human blood, and seismic bridge-bearings (a joint venture with Italy's fip Industrial). All but DMI resulted in substantial losses and writeoffs—and took critical attention and resources from Quixote's highway-safety business.
