Bell’s speech—called “Prizes for the Inventor: Some of the Problems Awaiting Solution”—reflected on a century of progress and looked ahead with remarkable foresight. In it he marveled at the advances made in the past century: Gas lighting had evolved into electric bulbs, humans could “see our own hearts beat,” and automobiles replaced horse-drawn vehicles. He then went on to predict the commercial airplane, solar panels, and the need for renewable resources. Now, one hundred years later, Bell’s predictions and warnings remain prescient.
