Today´s Engineering Heroes

Last July, IEEE Spectrum chall enged readers to identify today\´s unsung engineering heroes???those worthy engineers who are making a difference in the world and yet have not received the recognition they deserve. As author G. Pascal Zachary noted, engineering suffers from an unusual lack of heroes. "The hero deficit is???bad for engineering," he added, "because it diminishes the enterprise in the eyes of the public, and it constricts the flow of talent into the field."
