They are the invisible heroes in business, the men and women who make innovation possible. They are people like Mary Ann Wright at Johnson Controls in Milwaukee, the former chief engineer for the Ford Escape hybrid who is leading a team bent on establishing world leadership in hybrid battery systems.

Or Werner Zobel, a Modine Manufacturing engineer working in Germany who hatched the idea for a new cooling system that the Racine-based company believes could be revolutionary. The system uses ultra-thin layers of aluminum to dissipate heat, a breakthrough that has potential for car and truck radiators and air conditioning condensers.

Intellectual candlepower will fire the regional economy, the Milwaukee 7 regional economic development group believes. Its strategic plan relies on innovation-driven manufacturers that are heavy with engineers. But across the region, those companies say they can’t recruit enough engineers, and they worry that shortages will worsen as baby boomers retire. Complicating the picture is a shortage of visas for foreign-born engineers and increased competition from rapidly developing economies in China and India for those students even when they complete their studies in the United States.

The University of Wisconsin-Milwaukee, Marquette University and the Milwaukee School of Engineering are racing to fill the pipeline. Marquette and UWM are promising expansive new buildings and increased enrollment of both undergraduate and graduate students.
